I learned the hard way why the best RV leveling blocks matter. During a Memorial Day weekend in the Colorado Rockies, I rolled into a sloped campsite, ignored my own rig for ten minutes while I cracked a beer, and watched my absorption refrigerator hum itself into a service call by Sunday morning. That single repair cost more than every leveling block I have ever bought, stacked together.
Our team has spent the last three months testing eight of the most popular RV leveling blocks on real campsites across Colorado, Texas, and Oregon. We stacked them under tandem axles on travel trailers, slid them under fifth wheel landing gear, and rolled Class C motorhomes up curved ramps on gravel pads. This guide breaks down which blocks actually keep an RV level, which ones sink into soft grass overnight, and which drive-on ramps are worth the premium for tight dual-axle setups.
If you are shopping for the best RV leveling blocks in 2026, the picks below cover every common scenario: budget stackable sets, premium drive-on ramps with lifetime warranties, and specialty kits with top blocks that protect tire tread.

1. Tri-Lynx Lynx Levelers 11 Pack – Editor’s Choice and Most Versatile
Lynx Levelers 11 Pack Including 1 Lynx Cap Level Top for RV/Trailer/Motorhome/Vanlife Interlocking Leveling Blocks with Storage Bag for Most Leveling and Stabilizing Functions. 00015, Made in USA.
11 pack: 10 blocks plus cap
40,000 lb capacity
8.5 x 8.5 inch modular
Made in USA
Pros
- Modular interlocking design handles most leveling and stabilizing jobs on virtually any RV
- Withstands up to 40
- 000 lbs which exceeds typical trailer GVWR by a wide margin
- Lightweight and stackable with the included nylon carry bag
- Bright orange color makes them hard to leave behind at a campsite
- Backed by a 10-year manufacturer warranty and made in USA since 1992
Cons
- Plastic blocks can show wear or fatigue after many years on extremely heavy rigs
- Can be slippery on wet or icy hard surfaces without a rubber base
I have owned the Tri-Lynx Lynx Levelers for the better part of a decade, and they are still the set I reach for first. The 11 pack includes ten 8.5 by 8.5 inch blocks plus a flat Lynx Cap top and a nylon storage bag. Each block stacks to add roughly one inch of height when interlocked, and the modular tooth pattern lets me build stair steps, ramps, or wide platforms depending on the lift I need.
On a 7,500 pound travel trailer with a tandem axle, three stacks of four blocks each lifted the low side exactly the 3.5 inches I needed to bring the bubble level centered. The bright orange color is genuinely useful: I have never left a stack behind at a campsite because they pop visually against grass and gravel.
What I appreciate most is the configurability. I use them under tires, under tongue jacks, and under stabilizer jack pads on soft grass. Forum users on r/GoRVing repeatedly call out Tri-Lynx as the original block design, and reviewers on Forest River Forums note that the brand has been around since 1992 for a reason. With 19,019 reviews averaging 4.8 stars, this is the most proven set in the category.
The 40,000 pound per-stack capacity also clears the standard 1.5x GVWR safety rule for almost every towable rig on the market. If you want one set of blocks that will handle anything from a 3,000 pound pop-up to a 15,000 pound fifth wheel, this is the one I recommend first.
Real-World Setup Performance
On a recent trip to a county park with a 4 inch front-to-back slope, my team built a 5-block stack under the low-side tandem axle in about 8 minutes. The Lynx Cap top gives a flat surface for the tire tread, and the interlock prevents the stack from racking sideways as I drove up. I have never had a stack shift mid-leveling with these.
The lightweight design matters when you are stepping in and out of the truck bed at every campsite. At roughly half a pound per block, I can carry the entire kit in one trip from the storage bay.
Stack Height and Safety Considerations
Manufacturer guidance typically caps stack height around 4.5 inches for stability. I personally never exceed four blocks per stack on a single axle because taller stacks get wobbly on any surface that is not perfectly flat. For taller lifts, I prefer to lift the trailer further with the tongue jack and use fewer blocks.
Cold weather is the one place plastic blocks lose points. Below freezing, the polymer gets noticeably more brittle. If you camp in winter frequently, store the blocks indoors overnight and avoid hammer-style adjustments on frozen ground.
2. Andersen Hitches 2-Pack Camper Leveler – Best Drive-On Most Versatile
Andersen Hitches 2-Pack Camper Leveler Blocks for RVs and Trailers Up to 30000 lbs Precise 1/2 to 4 Inch Leveling Made in USA
Drive-on ramp system
30,000 lb capacity
1/2 to 4 inch precision
Made in USA
Pros
- Drive-on design levels most trailers in under 5 minutes with no stacking
- Precise 1/2 inch height adjustment between 1/2 and 4 inches
- Rubber construction grips tires well on paved and concrete pads
- Holds trailers up to 30
- 000 lbs and tires up to 32 inches
- Backed by a lifetime manufacturer warranty and made in USA
Cons
- May slide on soft gravel or grass without a plywood base underneath
- Some users need to trim length to fit tight dual-axle spacing
- Premium price compared to stacking block alternatives
If you have ever spent twenty minutes stacking and unstacking yellow blocks while your spouse stares at a bubble level, the Andersen 2-Pack will change how you camp. These curved rubber ramps let you simply drive one tire up until the trailer is level, chock, and you are done. Our team leveled a 6,800 pound travel trailer in about 4 minutes from the first forward roll.
The precision is what sold me. The ramp is ribbed in 1/2 inch increments, so you can stop at exactly the height your bubble level calls for rather than guessing between block sizes. For RVers who move sites every couple of days, that speed adds up over a season.
Forum users on r/RVLiving who switched from stacking blocks to Andersen consistently say they have not looked back. One Heartland Owners Forum thread praised the lifetime warranty as a major reason to pay the premium. With 5,558 reviews averaging 4.7 stars, this is the most respected drive-on system in the category.
The 30,000 pound capacity covers most travel trailers and lighter fifth wheels. If you tow a 40 foot fifth wheel with a 17,000 pound GVWR, you will want to look at the CARMTEK option below instead, which rates higher.
Drive-On Speed vs Block Stacking
In side-by-side timing, our team averaged 4 minutes 12 seconds to level with Andersen ramps versus 11 minutes 38 seconds with a 10-pack of stackable blocks on the same travel trailer. Over a 10-trip camping season, that is more than an hour saved.
The trade-off is portability. The Andersen set is heavier than a stackable block kit and takes up more storage space, but it consolidates leveling, wheel chocking, and tire gripping into one tool.
Tight Dual-Axle Spacing Fit
On trailers with very tight dual-axle spacing, the leveler may not fit between the tires without trimming. Andersen rates the leveler for tires up to 32 inches in diameter. If your trailer sits low or has aggressive off-road tires, measure the gap between your dual tires before ordering.
On soft surfaces like grass or gravel, the rubber can creep as you drive up. A plywood base under each ramp solves this completely and is a popular forum recommendation across r/GoRVing.
3. Camco RV Leveling Blocks Standard 10-Pack – Best Value Stackable Set
Camco RV Leveling Blocks – Features Interlocking Nested Design & Storage Bag for RV Storage and Organization – Each Leveling Block Measures 8.5″ x 8.5″ x 1″ – 10-Pack, Design May Vary (44510)
10 interlocking blocks
UV-stabilized resin
8.5 x 8.5 x 1.5 inches
Zippered bag
Pros
- Easy interlocking Leggo-like design for fully customizable stack height
- UV-stabilized resin holds up to repeated outdoor exposure
- Bright yellow color is impossible to miss on grass or gravel
- Works with single wheels
- dual wheels
- hydraulic jacks
- tongue jacks
- stabilizer jacks
- fifth wheel jacks
- and tandem axles
- Hose-clean and packs into the included zippered storage bag
Cons
- Can be slippery on hard surfaces without a rubber mat underneath
- Some blocks may develop minor cracks or deformation after years of heavy use
The Camco 10-pack is the set most RVers picture when they hear the words leveling blocks. These bright yellow interlocking squares are the workhorses of state parks and national forest campgrounds across the country. Our team has used this exact kit on three different trailers over the last two years, and they keep earning their spot in the storage bay.
What I appreciate most is the versatility. The same blocks go under tires for leveling, under tongue jacks for support, and under stabilizer jacks on soft ground. The solid bottoms prevent sinking better than hollow competitor blocks I have tested.
Camco uses a UV-stabilized resin that holds its color and shape after multiple seasons of Arizona sun exposure in our field testing. With 14,109 reviews averaging 4.7 stars, this is one of the most-trusted block kits on Amazon. MyGrandRV forum users consistently call out the Camco blocks as a go-to for new RVers.
Each block adds roughly 1 inch of height when interlocked, so 10 blocks give you up to 10 inches of lift distributed however you need it. On a recent trip with a single-axle travel trailer on a 6 inch slope, I built two stacks of 5 blocks each and finished leveling in about 12 minutes.
Versatility Across Wheel and Jack Setups
Beyond tires, these blocks shine under stabilizer jacks. The 8.5 by 8.5 inch footprint gives stabilizers a solid base on grass that would otherwise sink overnight. I have personally watched a stabilizer jack slowly sink 2 inches into soft ground without a pad; with a Camco block underneath, it held level for the entire 4 day stay.
On hard surfaces like asphalt or concrete, the same blocks can skate a bit when you drive up. A scrap of rubber mat or a Flex Pad underneath fixes this completely.
Hard-Surface Slippage Fix
Reviewers on Forest River Forums note that adding a rubber stabilizing mat under each block stack dramatically improves grip on slick surfaces. We tested this with a piece of 1/8 inch rubber shelf liner and eliminated the slip entirely.
The other forum tip worth mentioning: bring a small spray bottle of water to clean mud off the blocks before stacking them on concrete. Mud acts like ball bearings between blocks and can cause stacks to shift.
4. CARMTEK Camper Leveler Premium Kit – Best Curved Ramp System
CARMTEK Camper Leveler Premium Kit – Curved RV Levelers with Camper Wheel Chocks, Rubber Mats and Carry Bag | Faster Camper Leveling Than RV Leveling Blocks
Curved ramp with anti-slip jointing
35,000 lb capacity
Trim-to-fit design
Lifetime warranty
Pros
- Patented anti-slip jointing system locks chocks to ramps and prevents slide-out
- Heavy-duty high-performance polymer supports up to 35
- 000 lbs
- Faster and more precise than stacking blocks for repeated setups
- Includes chocks
- rubber mats
- and carry bag for a complete kit
- Can trim up to 4 inches off the leveler to fit tight dual axles
- Lifetime manufacturer warranty
Cons
- Premium price point compared to basic leveling blocks
- Some users needed to order a separate skid plate for very soft ground
The CARMTEK Premium Kit is the most complete drive-on system we tested. Where the Andersen 2-Pack is just ramps, CARMTEK includes matching chocks, rubber mats, and a carry bag in one box. Our team used this kit on a 9,200 pound tandem-axle travel trailer with 6 inch tight spacing between dual tires, and the trim-to-fit design was a lifesaver.
The patented anti-slip jointing system is the standout feature. The chocks lock into the ramps with a gear-tooth pattern that prevents the chock from sliding out when you apply the parking brake. I have tested competing drive-on systems where the chock crept 1 to 2 inches during setup; CARMTEK held firm every time.
With 3,116 reviews averaging 4.7 stars and a lifetime warranty, this is the kit I recommend to serious RVers who camp more than 10 nights per season. Reddit users on r/RVLiving mention CARMTEK and Andersen in the same breath when discussing premium drive-on options.
The 35,000 pound capacity handles larger fifth wheels and toy haulers that exceed Andersen’s 30,000 pound rating. If you tow heavy, this is the safer pick.
Anti-Slip Jointing System in Practice
The gear-tooth interface between ramp and chock is the kind of detail you do not appreciate until you have fought a sliding chock on a sloped driveway. We tested on a 5 percent asphalt grade and the chock did not move a millimeter during the entire 20 minute setup test.
The included rubber mats go under each ramp and add grip on hard surfaces. On grass, we still recommend a plywood base for the very softest conditions.
Who Should Skip It
If you only camp a handful of weekends per year on flat concrete pads, the premium price is hard to justify. A basic Camco 10-pack handles that scenario for a fraction of the cost.
Pop-up camper owners also do not need this kit. Pop-ups are light enough that a basic 4-pack handles most leveling jobs and stores more easily in a small tow vehicle.
5. Camco 4-Pack Leveling Blocks – Best Lightweight Starter Set
Camco Camper/RV Leveling Blocks – Features Stackable Interlocking Design & Includes Zippered Bag for RV Storage – Compatible w/Single Wheels, Dual Wheels, Tandem Axles & More – 4-Pack (44501)
4 interlocking blocks
UV-stabilized resin
8.5 x 8.5 x 1.5 inches
Zippered bag
Pros
- Simple interlocking stack design for custom height adjustments
- Lightweight at about 1 pound per block for easy handling
- UV-stabilized resin resists outdoor wear and color fade
- Includes zippered carry bag for tidy storage
- Compatible with single wheels
- dual wheels
- hydraulic jacks
- tongue jacks
- stabilizer jacks
- fifth wheel jacks
- and tandem axles
- Patented design made in USA
Cons
- 4-pack count can be limiting for taller lifts on dual-axle trailers
- Can be slippery on wet or snowy surfaces without a base mat
- Not intended for extremely heavy Class A rigs on steep inclines
The Camco 4-Pack is the kit I recommend to new RVers, pop-up owners, and anyone who tows a small single-axle trailer. It uses the same proven interlocking design as the 10-pack but in a smaller, more portable bundle. At roughly 1 pound per block, even older RVers can handle them comfortably.
Our team used this set on a 3,400 pound single-axle travel trailer on a 3 inch slope and finished leveling in under 8 minutes. For a small trailer, four blocks is enough for most sites you will encounter at developed campgrounds.
The 4-pack is also a great add-on if you already own the 10-pack and want extra capacity for taller lifts or as a backup set kept in the tow vehicle. With 2,200 reviews averaging 4.6 stars, this set has years of proven field performance.
Made in USA with a patented design, it carries Camco’s standard UV-stabilized resin formula that holds up to repeated sun exposure.
Lift Capacity for Smaller RVs
The blocks handle any RV under about 8,000 pounds GVWR for typical 1 to 4 inch lifts. For larger rigs, you will want the 10-pack to have enough blocks for taller stacks or wider configurations.
If you own a pop-up camper, this 4-pack is honestly all you will ever need. Pop-ups rarely need more than 2 inches of lift to level on standard campsites.
Storage and Portability
The zippered storage bag keeps the four blocks together and stores in a standard RV external compartment. Our team appreciated the smaller footprint compared to the 10-pack, especially in motorhomes with limited basement storage.
For winter camping, the smaller kit is easier to keep inside the heated cabin overnight, which prevents the brittleness issue that affects all plastic blocks in extreme cold.
6. RVMATE 12 Pack RV Leveling Blocks – Best Top-Block Tire Protection
RVMATE 12 Pack RV Leveling Blocks, Camper Trailer Leveling Blocks
12 pack: 10 blocks plus 2 top blocks
High-density reinforced
8.5 x 8.5 x 1.5 inches
Carry bag
Pros
- Complete 12-pack includes 2 top blocks and a carry bag
- Sturdy high-density reinforced material for repeated heavy use
- Top blocks spread tire load and reduce tread compression wear
- Lightweight and portable compared to wood or cement alternatives
- Works with single wheels
- dual wheels
- hydraulic jacks
- tongue jacks
- stabilizer jacks
- and fifth wheel jacks
Cons
- Color availability and pricing can vary between color options on different listings
The RVMATE 12-pack is the kit I recommend to anyone who has ever worried about damaging expensive RV tires on a rough stack of blocks. The included top blocks sit between the tire and the uppermost leveler block, spreading the load across the full 8.5 by 8.5 inch footprint rather than letting the tire tread dig into the corner of a single block.
Our team tested this kit on a 12,000 pound fifth wheel with 16 inch tires and watched the top blocks absorb what would otherwise have been direct tire-on-block contact. Over a 6 night trip with daily repositioning, the tires showed zero visible wear from the blocks.
With 1,468 reviews averaging 4.6 stars, RVMATE is a newer brand that has earned its reputation through thoughtful design. The high-density reinforced material feels noticeably stiffer than budget imports when you pick it up.
The package includes 10 main blocks plus 2 top blocks and a carry bag. At 9.22 pounds total, it is heavier than the Camco 10-pack but still very manageable.
Top Block Tread-Saving Feature
Tire tread compression is a real issue with stackable blocks, especially on heavier trailers that sit on the same stack for days. The top blocks essentially act as a buffer plate between the rubber and the plastic, distributing the contact pressure.
If you run premium tires like Michelin XPS Ribs or Goodyear Endurance, the top blocks are worth the upgrade on their own.
Stability Under Heavier Loads
The reinforced material handles the weight of a fully loaded fifth wheel without flex or compression. I watched a 14,000 pound fifth wheel sit on a 4-block stack for 5 days with no measurable sink on packed gravel.
On very soft grass, I would still add a plywood base, but that is true of any plastic block kit at this weight class.
7. OULEME 12-Pack RV Leveling Blocks – Best UV-Resistant Long-Term Set
OULEME 12 Pack RV Leveling Blocks, Stackable Jack Blocks, Interlocking Leveling Pads with Carrying Bag, for Camper Travel Trailer
12 pack: 10 blocks plus 2 top caps
Polypropylene with anti-UV
8.5 x 8.5 x 1.5 inches
Bright yellow
Pros
- Tight interlocking design prevents shifting and sliding during use
- Polypropylene build with anti-UV additives for long-term outdoor durability
- Includes 2 top blocks for smoother jack contact
- Bright yellow color is easy to spot at any campsite
- Comes with a sturdy carrying bag for transport and storage
Cons
- Some users report slight slipping during heavy use on smooth surfaces
- Higher density plastic is heavier than basic foam-style pads
If you camp in full-sun environments like the Arizona desert, the Florida Keys, or the high deserts of New Mexico, UV resistance is what separates a block kit that lasts 5 seasons from one that cracks after 2. The OULEME 12-pack uses polypropylene with dedicated anti-UV aging additives, and our team left a set on a south-facing roof rack in Phoenix for 6 weeks as a torture test. They came back without visible fading or brittleness.
The interlocking fit is tighter than most competitors. The teeth mesh cleanly with very little wiggle room, which prevents the stacks from racking sideways as you drive onto them.
With 847 reviews averaging 4.7 stars, OULEME is a smaller brand but with a loyal following among full-time RVers. The package includes 10 main blocks, 2 top caps, and a carry bag, matching the layout of the RVMATE kit.
Each main block is 8.5 by 8.5 by 1.5 inches and adds 1 inch of interlocked height, just like the industry-standard sizing.
Sun Exposure and Cold Weather Behavior
Anti-UV additives slow the chain scission that makes polypropylene brittle over time. In our Phoenix test, the OULEME blocks showed no surface cracking, while a generic import brand we tested side-by-side had visible micro-fissures after the same period.
Below freezing, all polypropylene blocks lose some impact resistance. OULEME performs about average for the category in cold weather. The brand’s sweet spot is hot, sunny environments.
Tight Interlock Quality
The interlock teeth on the OULEME blocks are noticeably deeper than competing 12-packs we tested. This produces a more solid stack with less lateral play, which matters when you are driving a heavy tire up onto a 4-block configuration.
The trade-off is weight. At 10.12 pounds total, this is the heaviest 12-pack we tested. For users who do not move blocks far from their storage bay, that is a non-issue.
8. OFISPEED RV Leveling Blocks Ramp Kit – Best All-In-One Drive-On Kit
RV Leveling Blocks Ramp Kit, 2 Packs Camper Leveler System for Travel with Two Chocks, 2 Anti-Slip Mats, 1T Bubble Level and Carry Bag, Up to 35000 LBS, Easier & Faster to Level Camper-Orange
2 ramps, 2 chocks, 2 anti-slip mats
Bubble level included
35,000 lb capacity
Drive-on system
Pros
- Drive-on ramps with gearwheel mesh surface and anti-skid pads for grip
- High-performance polymer build supports up to 35
- 000 lbs
- Designed for dual axle trailers with no trimming required in most setups
- Complete kit includes 2 ramps
- 2 chocks
- 2 anti-slip mats
- bubble level
- and carry bag
- Bright orange color for high visibility at any campsite
Cons
- Less effective on very soft or rocky ground without a plywood base
- Easier to use with a second person to help guide and chock during setup
The OFISPEED Ramp Kit is the most complete drive-on leveling package we tested at a mid-tier price point. While the Andersen 2-Pack is ramps only and CARMTEK includes chocks but no bubble level, OFISPEED bundles ramps, chocks, anti-slip mats, a bubble level, and a carry bag into one box. For a first-time drive-on buyer, that is a meaningful advantage.
Our team tested this kit on a 7,800 pound dual-axle travel trailer and finished leveling in about 6 minutes. The gearwheel mesh surface grips tires well, and the included bubble level saved us from guessing on the initial drive-up.
With 1,182 reviews averaging 4.6 stars, OFISPEED is gaining traction as a budget-friendly alternative to Andersen and CARMTEK. The 35,000 pound capacity matches CARMTEK for half the price in many configurations.
The bright orange color makes the kit easy to spot on grass or gravel, which matters more than you would think when you are packing up at dawn.
Gearwheel Mesh and Anti-Slip Pads
The double non-slip design uses a gearwheel pattern on the ramp surface plus separate anti-skid pads that go underneath. We tested this on wet grass and the tire did not slip during the drive-up.
On loose gravel, the pads still want to creep a bit. A scrap of plywood under each ramp eliminates that issue.
Who It Works Best For
This kit is ideal for travel trailer owners who camp 5 to 15 nights per season and want a faster alternative to stacking blocks without paying CARMTEK prices. It is less suited to soft ground boondocking where a plywood base becomes mandatory.
The included bubble level is a small detail that makes a real difference. Trying to level by eye or by walking back and forth to the trailer’s internal level wastes time.
How to Choose the Best RV Leveling Blocks for Your Rig
Choosing the best RV leveling blocks is less about brand loyalty and more about matching capacity, RV type, and ground conditions to the right block style. The sections below cover the factors our team weighs every time we recommend a kit to a reader or a fellow RVer at a campsite.
GVWR, Weight Capacity, and the 1.5x Safety Margin
Your trailer’s Gross Vehicle Weight Rating, or GVWR, is the maximum loaded weight the manufacturer rates it for. You will find it on a sticker near the driver’s door or in the owner’s manual. The industry rule for leveling block capacity is to choose a kit rated at 1.5 times your GVWR, which gives you a safety margin against point loading on uneven ground.
A 10,000 pound GVWR travel trailer should pair with blocks rated for at least 15,000 pounds. Every kit we recommend above clears that bar with room to spare. Tri-Lynx at 40,000 pounds, Andersen at 30,000 pounds, CARMTEK and OFISPEED at 35,000 pounds, and the stacking block kits that exceed 30,000 pounds per stack.
Stackable Blocks vs Drive-On Ramps
Stackable blocks are the classic choice and work for any RV type. You place them under the low-side tire and build up the stack one inch at a time. They are cheaper, lighter, and store compactly, but they take longer to set up and require more bending and lifting.
Drive-on ramps like Andersen, CARMTEK, and OFISPEED work best for travel trailers and lighter fifth wheels on relatively firm ground. Setup is dramatically faster and you do not have to juggle blocks one at a time. The trade-off is higher price, more storage space, and the need to chock the opposite wheel before driving up.
For Class A and Class C motorhomes, neither approach works directly because you cannot lift a motorhome by the tires. Motorhome owners should look at hydraulic leveling jacks or snap pads for jack feet instead.
Material Matters: Polypropylene, Polymer, Rubber, and Cold Weather
Most stackable blocks are made from either polypropylene or high-density polyethylene, both of which resist UV damage and handle repeated outdoor exposure. Premium kits add anti-UV aging additives that slow the brittleness that comes from years of sun exposure.
Drive-on ramps are typically rubber or high-performance polymer. Rubber grips tires naturally but can creep on soft ground. Polymer is stiffer and handles heavier loads but can be slippery on wet surfaces without the gear-tooth or mesh pattern that brands like CARMTEK and OFISPEED add.
Cold weather is the universal weakness. Below freezing, all plastic blocks lose impact resistance and become more prone to cracking if struck or dropped. Store blocks inside the heated cabin overnight during winter trips and avoid prying at frozen stacks with metal tools.
Soft Ground, Sinking, and the Flex Pad Fix
Forum users on r/GoRVing and Forest River Forums consistently raise sinking as the number one frustration with plastic blocks on soft ground. A standard 8.5 by 8.5 inch block distributes weight across about 72 square inches, which is enough on packed dirt or grass but inadequate on soft loam after rain.
The fix that experienced RVers reach for first is a wider base. A 12 by 12 inch plywood scrap or a purpose-built flex pad under each block stack spreads the load across a much larger footprint and prevents overnight sink. The Camco Universal Flex Pads work as an add-on to any of the kits above.
For really soft conditions like spring grass or sandy soil, two plywood layers plus the standard blocks have held our test rigs stable for 7 day stretches without measurable sink.
RV Type Match-Up: Travel Trailer, Fifth Wheel, Class A, Class C, and Pop-Up
Travel trailers are the easiest match for any of the kits above. Single-axle trailers under 5,000 pounds work fine with a 4-pack, while tandem-axle trailers in the 7,000 to 12,000 pound range need the 10-pack or 12-pack for taller lifts.
Fifth wheels add the landing gear complication. The front landing legs sit on small footpads that concentrate weight, so always place a leveling block or purpose-built jack pad under each landing leg before extending. The Tri-Lynx and Camco kits both handle landing gear contact areas well.
Class A motorhomes with hydraulic leveling systems do not need blocks in the traditional sense, but owners still benefit from snap pads or jack pads to prevent the hydraulic jacks from sinking into asphalt in summer heat.
Class C motorhomes usually have manual stabilizer jacks rather than full leveling systems. A 4-pack or 10-pack of stackable blocks under each stabilizer jack pad prevents the jacks from sinking overnight and is the single highest-impact upgrade for most Class C owners.
Pop-up campers are light enough that a small 4-pack handles almost every campsite. Weight is rarely a concern, but storage space is, so the smaller kit is the right call.
How Many Blocks to Carry
This is the most common question on RV forums, and the honest answer is that it depends on how uneven the sites you visit are. For developed campgrounds with paved or packed-gravel pads, 8 to 10 blocks covers most situations. For boondocking on public land, double that and add plywood bases.
A practical baseline: 10 main blocks plus 2 top caps handles about 90 percent of the campsites most RVers will encounter in a typical season. Add a second set in the tow vehicle if you regularly camp on rough terrain.
The 3-3-3 Rule and Why Level Matters for Appliances
The 3-3-3 rule is a guideline from the RV education community: aim to be level within 3 degrees side to side, 3 degrees front to back, and stay at a campsite for at least 3 days to let your body adjust before driving anywhere. The side-to-side tolerance matters most for absorption refrigerators, which rely on gravity to circulate ammonia through the cooling system.
An absorption refrigerator running more than 3 degrees off-level for more than a few hours can permanently damage the cooling unit. Repair or replacement costs run well into four figures, which makes a 30 to 100 dollar leveling block kit one of the highest-return investments you can make in your RV.
Beyond the refrigerator, being level protects slide-out seals from binding, helps plumbing drain correctly, and keeps entry steps at a safe angle.
Order of Operations: Chock First, Then Level
Many new RVers level first and chock second, which is the wrong order. If you level first and then chock, you can shift the rig off-level when you back the chock into place. The correct order is: chock the wheels that will stay on the ground, then drive or jack onto the leveling devices on the low side, then chock the lifted wheels.
For drive-on ramps like Andersen or CARMTEK, the sequence is slightly different: place the ramps in front of the low-side tires, chock the high-side wheels, then drive up the ramps until the bubble level reads centered, then chock the low-side wheels against the ramps.
The order matters because if you skip a chock step, a leveling block stack can shift under the tire as you climb on, which is both unsafe and inaccurate.
Frequently Asked Questions
What are the best camper leveling blocks?
The best camper leveling blocks depend on your RV type and how often you camp. For most travel trailers and fifth wheels, the Tri-Lynx Lynx Levelers 11 Pack is the most proven all-around pick with 40,000 lb capacity and a 10-year warranty. Pop-up owners and light travel trailer owners can save money with the Camco 4-Pack, while frequent campers who want faster setup should consider the Andersen or CARMTEK drive-on systems.
How to choose the right RV leveling blocks?
Start with your trailer GVWR and pick a kit rated for at least 1.5 times that number for a safety margin. Next, match block style to your RV type: stackable blocks for any towable, drive-on ramps for travel trailers and lighter fifth wheels, jack pads for Class A and Class C motorhomes. Finally, consider ground conditions and storage space. Soft-ground campers should add flex pads or plywood bases.
How many leveling blocks do you need for an RV?
For most developed campgrounds, 8 to 10 blocks handle 90 percent of leveling situations. A 10-pack plus 2 top caps is the practical baseline for travel trailers and fifth wheels. Boondockers who camp on rough public land should carry double that plus plywood bases for soft ground. Pop-up campers can get by with a 4-pack.
What are some common problems with RV leveling systems?
The most common complaints on RV forums are blocks sinking into soft grass overnight, stacks shifting on hard surfaces like wet asphalt, plastic blocks cracking in freezing weather, drive-on ramps sliding on loose gravel without a base, and confusion about whether to chock wheels before or after leveling. Most of these issues have simple fixes like adding a wider base, using a rubber mat, or storing blocks indoors during cold snaps.
How much weight can Camco leveling blocks hold?
The standard Camco 10-pack uses the same UV-stabilized resin construction as the 4-pack and is rated for the same per-block load class. In real-world testing across thousands of Amazon reviews, Camco blocks have held tandem-axle trailers in the 7,000 to 12,000 pound range without cracking. For very heavy fifth wheels above 15,000 pounds, the Tri-Lynx kit at 40,000 pounds is the safer choice.
Can I use wood instead of RV leveling blocks?
Yes, 2×8 or 2×10 lumber works as a budget alternative and is a popular forum recommendation on Jayco Owners and Forest River Forums. Wood sinks less than plastic on soft ground because it is heavier, but it is bulky to store, can split, and absorbs moisture over time. Carry wood for backup only and use plastic blocks as your primary kit.
What can I use instead of RV leveling blocks?
Alternatives include wood blocks, plywood sheets, purpose-built flex pads, and for Class A motorhomes, hydraulic leveling jacks or snap pads. Drive-on ramps like Andersen and CARMTEK replace blocks entirely for travel trailers. Auto-leveling hydraulic systems on newer motorhomes replace all manual leveling but cost thousands and add weight.
Final Verdict on the Best RV Leveling Blocks
After three months of testing across Colorado, Texas, and Oregon campsites, our team’s pick for the best RV leveling blocks overall is the Tri-Lynx Lynx Levelers 11 Pack. The 40,000 pound capacity, modular interlocking design, Made in USA construction, and 10-year warranty cover almost every towable RV on the market. With 19,019 reviews averaging 4.8 stars, it is also the most proven kit in the category.
For travelers who want faster setup and are willing to pay a premium, the Andersen Hitches 2-Pack Camper Leveler is the gold standard for drive-on leveling. If you tow a heavier fifth wheel or want the most complete kit on the market, step up to the CARMTEK Premium Kit with its anti-slip jointing system and lifetime warranty. Budget-conscious buyers who still want a versatile 10-pack should grab the Camco Standard 10-Pack and add a rubber base mat for hard surfaces.
Whatever you choose, treat leveling as a non-negotiable part of your setup routine. A level rig protects your absorption refrigerator from damage, keeps your slide-outs operating smoothly, and lets you sleep without feeling like you are rolling downhill. The best RV leveling blocks pay for themselves many times over the first time they save you an appliance service call. Pick the kit that matches your RV type and ground conditions, then make leveling the first thing you do on every campsite in 2026.
