Review on 🔶 Camco 21023 FasTen 4x2 RV Leveling Block Set - Dual Tire Stacking with Interlocking Design - Includes T-Handle Carrying System - Yellow (Pack of 10) by Adam Johnson

I bought these to replace the old 2X6 wood I used to carry in my RV. They are far superior in design and use. I bought a 4X2 (17"X 8.5") instead of a 2X2 for my single wheel camper because you can build interconnected stages (long way 2X2 open) which allows you to build higher level blocks. When you stack 2x6 or 2x2 aligners on top of each other they tend to "spout out" from under the tires. It's not like this. One caveat is that if you're on mud, mud, or gravel, I would recommend that you put a 1/2 inch piece of plywood cut to 18"X9" underneath to stabilize them and close prevent them from warping - for soft or uneven surfaces.
