I saw these a couple months ago. After our last trip with trying to get wood planks under the one side to get the TT level I searched and found these easy to use trailer levelers. I contacted Anderson...
It seems like we get at least one day of rain, which coats everything on the ground with sand. I like to pack things up nice and clean. Plastic is easier to wash and dries faster than wood. I like 'em. Thanks for the tip!
