I've seen those before. Pretty darn expensive, but if it assists in entry / exit of the RV, then price doesn't matter. We had our entry steps changed from a 3 to a 4 step model before we'd accept it. In our case, it was for the little ones as their short legs don't do so hot on a 3 step and the high entry door on the fifth wheel.
I like the looks of it, and the fact it folds up fairly small and has a handrail.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
