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...
I to use wood 2 X 8's for leveling. I'm curious to see how you like this product. On another note, why don't campgrounds level their sites? Last week we were at a beautiful campground which had a stone drive to park on, concrete pad for the picnic table and paved roads. But, the stone drive that we parked on was about 2" out of plumb. It could be leveled with a rake...
Obviously, for boon docking or state / national parks with grass sites we still need to level.
