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

I have no experience with those steps but like you said, not sure they are meant for a door that high off the ground.

My current camper has a nice built in step but on my last one I didn't like the scissor steps either so I used a Little giant safety steps. It's like a portable staircase. I'm thinking you'd probably want the 4 step model.
