Hate 'em, hate 'em, hate 'em. They have to be adjusted for almost every time they are deployed. We have had to move the trailer because the ground was too close to the trailer, and we couldn't shorten them enough to use them. Luckily we have a toyhauler with the second door which doesn't have the solid steps. Otherwise we wouldn't be able to get into our trailer when it's in storage.
I wish the guy that thought those up had mine in his "basement".
