When figuring out the layout for our camper, I struggled with the entry ladder situation. The side door on the flatbed is a little higher than the door on the slide in camper, and entry/exit from a FWC is already a little awkward due to the hobbit door. I spent way too much time perseverating on this, but eventually came up with a pretty good solution - half of a 'little giant' step ladder. This provided, large, flat, grippy and stable stairs - perfect for backing out of the camper, after dark with two beverages in hand. These have worked pretty well over the past couple of years, and I think a few others have adopted the idea:
Unlike some of my other ideas, this one worked pretty well first time, and hasn't needed a complete redesign. But there was some room for improvement. The first issue is the length of the ladder. I have the 4-step model, and on flat ground it was a tad too short - not a huge deal, but this did give the steps a slight downward slope away from the camper. On uneven ground this could be pretty significant slope (particularly with leveling blocks under the wheels) leading us to use a 2x4' under the feet to make it more level, and sometimes rocks and logs and whatever else was at hand. This did not contribute towards my goal of a stable ladder, or help with the evening beverages. So revision B of the ladder includes adjustable legs, short mode:
Long mode:
