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.

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 leveling blocks work very well for our Airstream interstate 19. They pack very compactly and seem to stay in place when we are upon them. I would recommend they be purchased if you need a set of leveling box

Decent device to level the RV.

I used these on my first RV camping trip. I was on a not very level site and these worked well to level my camper. They worked so well I ordered another set. The handle is great at keeping the blocks together.

Bought these at the start of our camping season. I really prefer these to the ones you drive up on that are like a ramp. Besides leaving out under your wheels they can be used for your stabilizer feet as well or your hitch. Quality is great I have not had one crack, I was worried these would be too big to pull my tires over easily but that wasn’t a problem at all. The size allows you to group them together like legos to do what you need to get level. They come in a bundle with a handle that secures them all together in a nice lightweight block that’s easy to store. I actually bought a second set for my fifth wheel after buying the first set. I got them both on sale and am very very happy with them.

So I’ve used wood over the years to level out my Class A RV’s and even with the wood sealed, there is always one side that takes a beating. I figured I would try these Camco rectangular leveling blocks and was very surprised at their strength. I’ve only used them twice, but both times the RV rolled right up with no issues. The RV sitting on those blocks in the picture is a 40’ Tiffin diesel pusher. My only issue is the dual wheel base for this big RV, is too wide to use the blocks perpendicular to the wheels, so I had to use 3 blocks parallel (see pics) for each wheel, which required me to purchase two sets. Most sites I setup up at fairly level, but this just provides that little extra height if needed.

works great

The leveling blocks do what they say they will do and are easy to use. They are heavy when all together but each individually are light. The one downside is they will sink into soft ground and if on gravel the stones get caught in them but come out easily with a light tap or use a hose. Suggest putting down a piece of wood on ground if soft then the blocks to prevent them from sinking into ground which also seems to warp them from the weight.

Great product, easy to use, packs up nicely, I might have to get one more,

Works well on our class c motor home with dual rear wheels. Easy on/off.

Easy to use

Great for leveling the motorhome on concrete and softer ground.

I'd imagine not so good on gravel though
