Review on 🚧 RV Leveling Blocks - Heavy Duty Rubber Dual Wheel Chocks with Non Slip Base, Yellow Reflective Tape and Nylon Rope - Ideal for Travel Trailers, Cars, Campers, Trucks - 1 Pair by Joshua Pilla

These are chocks and it looks like they will work. Each block is clearly sewn from two separate pieces of rubber and not a single piece sold. I was a bit disappointed to see this but hopefully it won't be a problem. That being said, this is exactly the type of pad I wanted as it runs simultaneously on both tires of my two-axle trailer, which is the shape we use on airplanes. I figured if it worked for the 777 it would work for my trailer too. They're nice and heavy, which is good for a last, keeps them from moving and means they're tight enough to resist rolling.
