An uneven campsite can leave your RV floor sloped, make doors swing, and complicate appliance setup. The Camco RV Leveling Blocks 10-Pack gives you a compact way to raise a low wheel or create a broader base beneath compatible jacks. Its interlocking design is simple to store and adjust, but it still requires careful placement, a firm surface, and separate wheel chocks. This review helps you decide whether Camco model 44510 fits your RV setup and camping routine.
Quick Verdict
Rating: 8/10
Best For: RV owners who want stackable blocks for tire leveling, jack support, and compact storage.
Bottom Line: The 10 interlocking blocks offer flexible height adjustment and broad compatibility with common RV wheel and jack setups. They are less convenient than a curved drive-on leveler when you want continuous height control, and they do not replace wheel chocks.

Key Takeaways
- The set includes 10 interlocking blocks that let you build a custom platform instead of carrying loose wood boards.
- Each added block increases the stack by about 1 inch, so you can make step-by-step adjustments.
- The solid-bottom design helps spread the load and reduce sinking on grass or soft soil, but the ground still needs to be firm and stable.
- The blocks are listed for use with several wheel and jack arrangements, although you should confirm fit and limits in your RV manual.
- You still need proper wheel chocks after leveling because these blocks are not designed to stop an RV from rolling.
What Are the Camco RV Leveling Blocks?
Camco model 44510 is a 10-piece set of square, interlocking blocks for adjusting an RV’s parked height. You can place a platform beneath the tire or tires on the low side, then drive onto the stack slowly. The blocks can also provide a wider contact surface beneath compatible tongue, hydraulic, stabilizer, or fifth-wheel jacks.
The blocks nest together for storage and come with a zippered carrying bag. Their bright yellow finish makes them easier to see during setup and final campsite checks. Camco lists the product as a design-may-vary item, so check the current listing photos and package details before ordering.
Before You Buy: Leveling blocks raise a low wheel or support a compatible jack, but they do not replace wheel chocks or your RV’s stabilizing system. Confirm tire width, jack-foot size, loading limits, and stacking instructions before use.
Who Should Buy It?
Best For
- Travel-trailer and camper owners who regularly park on slightly uneven sites.
- RVers who want one portable set for tire leveling and compatible jack support.
- Buyers who prefer fixed, one-inch height steps and compact nested storage.
Skip If
- You want continuous height adjustment without stacking and repositioning blocks.
- Your dual tires or large jack feet need a wider platform than this set can safely create.
- You need a product with a clearly published load rating for a specific heavy-rig setup.
Build Quality and Interlocking Design
The blocks use UV-stabilized resin for repeated outdoor use. That material keeps the set lighter and easier to handle than wood planks, while the square shape gives you several layout options. The solid bottoms also create more surface area against the ground than open-grid blocks.
The interlocking edges help keep adjacent blocks aligned when you build a platform. This does not make every stack automatically safe. You still need a broad base, full engagement between blocks, and a layout that follows Camco’s directions and your RV manufacturer’s guidance.
Fit and Compatibility
Camco lists the blocks for single wheels, dual wheels, tandem axles, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth-wheel jacks. That range makes the set useful for more than one campsite task, especially when you want to reduce jack extension or keep a jack foot out of mud.
Compatibility is not the same as guaranteed fit. A wide dual-wheel setup may require more blocks than a single 10-pack can provide. Large jack feet can also overhang a small platform, so measure the tire contact area or jack foot before relying on the set.
Leveling Performance and Height Control
Each added interlocked block raises the stack by about 1 inch. This fixed-step system works well when your campsite is only slightly off level and you can estimate the needed lift with a bubble level or your RV’s built-in leveling display.
The main tradeoff is adjustment speed. You may need to build the platform, drive onto it, check the level, then reposition or add a block. A curved leveler offers finer adjustment in one drive-on motion, but stackable blocks give you more layout flexibility and can double as jack pads.
Pro Tip: Arrange the blocks before moving the RV, then use a spotter when possible. Stop, set the parking brake, and recheck the platform before chocking the wheels and continuing setup.
Storage, Visibility, and Cleaning
The 10 blocks nest into a compact stack and fit inside the included zippered bag. This keeps dirt away from other gear and makes it easier to count the blocks before leaving a campsite. The yellow color also stands out against gravel, grass, and pavement.
After use, remove loose stones and mud with water. Let the blocks dry before closing the bag, and inspect the interlocking edges and solid bottoms for cracks, warping, or deep damage. Replace any block that no longer sits flat or locks securely.
How It Performs in Real Use
On a Slightly Sloped Campsite
For a small side-to-side correction, the one-inch steps are easy to understand. You can build a short ramp and platform under the low-side tire, move the RV slowly into position, and check the level again before final setup.
Under a Tongue or Stabilizer Jack
A block platform can reduce how far a compatible jack must extend and can provide a cleaner contact point than bare soil. The platform must fully support the jack foot, and stabilizer jacks should be used for stabilization rather than lifting unless your RV manufacturer specifically says otherwise.
On Grass or Soft Soil
The solid bottoms help spread contact over the ground and may reduce sinking compared with a narrow jack foot. They cannot make saturated, loose, or unstable ground safe, so move to a firmer area when the surface shifts or compresses.
For Travel and Repeated Setup
The nested stack and storage bag are practical when cargo space is limited. The set is also easier to clean and replace than improvised lumber, although repeated loading and rough ground can still damage resin blocks over time.
How to Use Camco Leveling Blocks Correctly
- Check the site first. Choose firm ground and identify which side or corner is low.
- Measure the correction. Use a bubble level, built-in system, or approved leveling tool to estimate the needed lift.
- Build a stable platform. Interlock the blocks fully and keep the base wider than the upper layers. Do not build a narrow tower.
- Position the platform. Place it in the tire path or beneath the compatible jack point without placing your body under the RV.
- Move slowly. Use a spotter when available and stop as soon as the tire is centered on the platform.
- Secure the RV. Set the parking brake and install proper wheel chocks before unhitching or continuing setup.
- Recheck everything. Confirm the blocks sit flat, the tires or jack feet are fully supported, and the RV is level.
Follow the product instructions and your RV owner’s manual for the approved sequence, jack use, and load limits. Never crawl beneath an RV supported only by leveling blocks or stabilizer jacks.
Compatibility and Setup Safety
Use the blocks only on a surface that can support the RV without shifting. Keep hands, feet, and loose items away from the tire path while the RV moves. If a platform bends, cracks, slides, or sinks, stop and rebuild on firmer ground or use a different leveling method.
Wheel chocks are a separate safety item. Place them according to your RV manufacturer’s instructions after leveling and before unhitching. Leveling blocks also do not turn stabilizer jacks into lifting jacks, so use each part of your RV only for its approved purpose.
Pros and Cons
Pros
- Ten interlocking blocks provide several platform layouts.
- About one inch of added height per block makes adjustments easy to plan.
- Solid bottoms help spread contact on grass, soil, and gravel.
- Listed for common tire, axle, and RV jack arrangements.
- Bright yellow blocks nest into the included storage bag.
Cons
- Fixed height steps can require several attempts to reach the right level.
- One 10-pack may be too small for wide dual tires or several jack points at once.
- The current listing does not give a clear load rating for every possible RV setup.
Is It Worth the Price?
The Camco 10-pack is a practical mid-range choice when you want reusable leveling blocks that can serve more than one purpose. It offers the most value to RV owners who need occasional tire lift, jack support, and compact storage without buying separate pads for every task.
Its value drops if you need a wider heavy-rig platform, a published setup-specific load rating, or continuous height adjustment. In those cases, a larger block system or curved drive-on leveler may be a better match.
How It Compares to Alternatives
The Andersen Camper Leveler uses a curved ramp to provide continuous adjustment from about 1/2 inch to 4 inches, which can be faster for leveling a trailer tire without stacking blocks. Camco’s FasTen Premium RV Leveling Ramps offer another drive-on design and up to about 2.5 inches of tire lift.
The Camco 44510 blocks make more sense when you want modular pieces that can also sit beneath compatible jacks. A curved leveler is better when fast, fine tire-height adjustment is your main priority.
Frequently Asked Questions
Can Camco leveling blocks be used with every RV?
Camco lists model 44510 for several wheel, axle, and jack arrangements, but fit depends on tire width, jack-foot size, and the RV’s weight and instructions. Measure your setup and confirm approved use before buying.
How many blocks do you need to level an RV?
There is no universal number because the answer depends on the slope, number of tires, and platform width. A 10-pack can handle many small corrections, but a dual-axle or multi-jack setup may need another set.
How much height does each block add?
The product listing describes about 1 inch of added stack height for each interlocked block. Actual setup height can depend on the pattern and how the blocks engage.
Can you use the blocks under RV jacks?
They are listed for compatible hydraulic, tongue, stabilizer, and fifth-wheel jacks. The jack foot should remain fully supported, and you should follow the RV manual because stabilizer jacks are not automatically approved for lifting.
Do leveling blocks replace wheel chocks?
No. Leveling blocks raise or support the RV, while wheel chocks help prevent rolling. Use proper chocks after leveling and before unhitching or moving around inside the RV.
Can you use them on grass or soft ground?
The solid bottoms help distribute contact and reduce sinking, but they cannot stabilize saturated or loose ground. Inspect the surface, watch for settling, and move to firmer ground if the platform shifts.
How should you clean and store the blocks?
Hose off dirt and stones, allow the blocks to dry, and nest them inside the zippered bag. Inspect each piece before the next trip and replace blocks that are cracked, warped, or unable to interlock securely.
Do Camco RV Leveling Blocks have a warranty?
Current product information lists a limited one-year warranty. Warranty terms can change, so confirm coverage, registration steps, and proof-of-purchase requirements with Camco or the seller.
The Bottom Line
Camco RV Leveling Blocks model 44510 is recommended for campers who want a flexible 10-piece system for small height corrections and compatible jack support. Its interlocking layout, solid bottoms, visibility, and storage bag are useful strengths, but buyers with wide dual tires, very heavy rigs, or a need for fine continuous adjustment should compare larger platforms or curved levelers.
