Camco FasTen Camper / RV Leveling Blocks - Features Interlocking Design for Customizable Height - Carrying Handle Twists to Secure Blocks for RV Storage - 17” x 8.5” x 1”, Yellow, 10-Pack (21023)

Very easy to use, we have used these both for leveling our trailer in uneven campsites and to act as a level for our jacks. These worked well for both purposes. These are made of hard plastic and I had fears they may crack with the weight of the trailer on them but they have held up well. Ours have been dropped on concrete multiple times and we have yet to get any breaks or cracks. Great leveling blocks.

Nice

I have one set of these already. Adding this second set will give me greater ability to get our class "C" motorhome level where at some of the State Parks we visit, there can be varying degrees of slope. These blocks stack easily and I like the convenient carrying handle. They are pretty sturdy too.

works as intended

nice compact package to store

These things are amazing, they stay together even when we have to move to adjust. I constantly get other RVers asking what brand they are and where we got them.

They looked to crush a little bit and sink in a good bit when I put them on south FL grass/sandy loam. But they did the job and took back to shape without much bend. I really liked them and am getting rid of my other leveling equipment. Nice light weight and plenty strong for my needs (gvwr about 15k). Plus can use under my tires or my jacks. I bought the caps and rubber bottoms for the jacks and to keep sinking in. A good buy for me.

I've purchased this item in the past so I knew what I should be receiving.The blocks came in a timely manner and joined my existing ones.Easy to use and store.I've had my first set for 6 years and continues to hold up well. I feel these will be as durable as well.

Made of strong plastic work perfect

Ease of use and strong

We have had the single leveling blocks for some time and four of the double leveling blocks, but because we have dual wheels on the back of our little motorhome we needed some more doubles. They work great, but can crack if place on an uneven rocky surface, so watch for that. They are easy to store when not in use. I would recommend them.

This blocks are good not only for leveling but to make steps.
