The ramps didn't slip when we went to level our RV. And no damage to the ramps after our first use. (approximate weight on each ramp was 1500 pounds. Well under the max rated load.) We tried the yellow blocks with the same load from another store and they were damaged to the point of being almost useless after one use.

Ex Output:

positive
