Review on Homeon Wheels RV Leveling Blocks - Camper Leveler Kit with Curved Levelers, Chocks, Grip Mats, Level, and Bag - Supports up to 30,000 LBS - 2-Pack Black by Jason Ortiz

Overall I am very happy with these leveling blocks. They worked to level the trailer on all the bumps we recently parked our trailer on. We haven't had any extreme cases where one side deviated more than 3-5 inches. The non-slip pad is a nice touch. This pad helped in some spots where the blocks were slipping without using the pad. The only problem I had was when using them on my paved road. The little rubber feet in the blocks stick to my hot asphalt when the temperature is above 30 degrees F. I add some JB Weld so they stick forever. The only other minor thing we noticed is that these blocks aren't very wide. My trailer has fairly wide off-road tires, but we found the blocks to work well despite being narrower than the tire width. As long as you center them in the middle of the tire there shouldn't be any problems.
