Okay I finally go a 3 step little giant ladder. OH MY am I pleased. I am using this with my truck camper and its as though these steps where designed for my truck camper. The three step unit is just a inch shy of being level with my step bumper. The steps are unbelievable solid and remain so on unlevel ground. I could see maybe having a couple small maybe 3" by 3" 1/2 plywood shims for really irregular ground. But so far I a haven't need a thing. I have used the unfolding accordion steps and I have made my own extra step to use with the the lance fold down step. But these don't come close to how well the little giant steps work. When towing my fishing boat I leave it connected to the truck all the time. I can turn the little giant sideways and it makes a perfect side entry platform. Just like I have a fancy camper. This is just one more vote for little giant. I can't see anything being better for a truck camper. JMHO
