Anyone use ' "Solid Step" stairs? for Truck Camper

I should have mentioned that the TL Glow Step Revolution system has an adjustable top step so it can be closer or further away from the entrance step; that, in addition to the independently adjustable height landing legs designed to compensate for unlevel ground, makes this the best step system I've used in more than 40 years of motorhome, 5th wheel, travel trailer and TC ownership.......
