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)

These are great toppers if you are short on space and want to put these on top of the blocks to create a flat surface. I used them for my little camper, and they worked great. Saved me from having to purchase a set of risers! Easy to use, fits on the companion blocks, hard to lose yellow. Takes much less space than the blocks. I put them on top of the blocks that I use with the levelers when camping in a field. Keeps the camper levelers from sinking into the mucky grass.

This review is for the FasTen XL 10 pack (10.5" × 10.5", 10 ea.). We have a 2024 AWD Sprinter van that's been fully converted to a Class B camper. Fully loaded, the van weighs ~ 8,650 lbs, and sits on 265-mm-wide (10.4-inches wide) BF Goodrich AT KO2 tires. The width of the tires were a driving factor in deciding to purchase the XL-sized blocks instead of the standard blocks. In addition, each wheel carries more than a ton of weight, especially in the rear. To be honest, I had my doubts about how well these plastic blocks would stand up to such loads. I am happy to report that after three weeks of daily use on both dirt and paved surfaces, these blocks have performed very well, showing no signs of cracking or deforming. While in use, the blocks sometimes appear to be bent (and possibly they are, but this could also be an illusion). Nonetheless, when stowing them, the blocks are perfectly flat and stack nicely for easy storage in the van's equipment box. Just knock off the dirt and pebbles, stack them up using the convenient handle, and you're ready to go.

Way better priced than found at most RV dealers. Work great with my duel wheels.

I like these and like the packaging. I give it only 4 stars, because the only thing I don't like is the 4 raised parts on each. Instead of being completely flat like my others, they are sometimes difficult to use with smaller feet on things like steps and/or jack stands. In some cases, they can cause the feet to torque unnecessarily because it is between the raised section. I'd prefer that these be flatter on top, plus, they might match up with other manufacturers making them more usable in more situations. I'd still recommend them, but might consider an alternative if I were to buy again, knowing what I do now.

As an avid RVer, I can't emphasize enough how the Camco Fasten XL 2x2 Leveling Block has transformed my RVing experience. These leveling blocks are an absolute game-changer, and here's why: Interlocking Design: The interlocking design is ingenious. It allows for effortless customization of the height needed to level my RV, no matter the terrain. These blocks securely fasten together, creating a solid foundation, and there's no need to worry about them shifting or slipping. Stability and Durability: These blocks are incredibly sturdy. They can handle the weight of my RV without flexing or cracking. Even on uneven surfaces, they provide a stable platform, ensuring my RV stays level and secure. Convenience: The Camco Fasten XL blocks are a breeze to use. I appreciate that they come with a built-in handle for easy transportation and storage. Setting them up is quick, saving me time and effort when I arrive at a new campsite. Versatility: They're not limited to leveling alone. I've also used them to support my RV's stabilizer jacks, making them versatile tools for various aspects of RV setup. Quality Build: These blocks are built to last. They can withstand the rigors of outdoor use and are resistant to UV damage. I'm confident that they'll serve me well for many RVing adventures to come. In summary, the Camco Fasten XL 2x2 Leveling Block is an absolute must-have for RVers. They make leveling and stabilizing an RV a breeze and offer peace of mind in any terrain. These blocks have significantly improved my camping experience, and I highly recommend them to fellow RV enthusiasts.

These have proven very helpful for the purposes that I bought them for. One is to lift the front of my SUV a tad to make it easier to get beneath it for oil changes. There is just enough room as it is, but that extra +/- 2" just makes it that much easier to maneuver. Always use chocks and set the parking brake. Use jack stands if the vehicle's standard clearance would be at a crushing level and be mindful of any incline in the terrain. This can be more significant than is apparent. These are also useful when washing the vehicles tires. Otherwise it's difficult to next to impossible to get to the bottom edges of the tire that is sitting on the ground. We've all seen wheels that were cleaned with that one glaring strip that could not be reached for cleaning and tire gel that sticks out like a sore thumb. I am confident that these will perform well for my 17' tandem cargo trailer's tires and tongue jack, and same with my 19' travel trailer, both dual axle, though leveling blocks made for tandem tires would be a bit easier to use in lifting one side up a bit or protecting the tires from cement. One would also have to expect a certain amount of distortion if these are left under weight for extended periods. I see comments on people using wood, which is fine to keep tire contact off of cement, but wood splinters and cracks, so should never be used under a tongue jack if needed to secure the trailer at a height sufficient to maneuver the hitch ball beneath it. I read about these being crushed under a Class "A" RV-that is expecting these relatively inexpensive units to hold the stabilizing pressure of a bus. Others had similar but stories but failed to say what kind of rig that they attempted to use these under, nor did any mention the degree of incline that they were attempting to compensate for. Declaring "not for use with levelers" is an absurd exaggeration without specifics. "Not for use with a bus sized RV, on an incline, with slide outs extended" is one thing. Take a look at the grade of leveler used for demonstration, then look at the footprint of the huge hydraulic pad that this reviewer provided in her photograph, then look at her sweeping statement "since it did not work on my behemoth, it will not work under any circumstances, including your pop up camper!". Use some common sense here. These are built like large Legos. Look a the images provided for an idea of what kind of support that these are intended to provide. "Heavy Duty" is a relative term used in marketing that means nothing if no context is provided. Camco should be a bit more specific, but customers also need to use some common sense and exercise a bit of due diligence.

Easy to assemble and level the vehicle. Sturdy construction.

Works great at every site even if it is gravel.
