Best dog ramp getting out of CLASS A RV?

Over the year's I've tried several different approaches. First we had a single step outside to go with the retractable one, then we moved to a ramp which actually did allow us to use it too but could get slippery when wet so my latest solution is to add the carpeting to the inside steps then I went to work on making something for the retractable step because its so stiff and narrow. I built a 2x4 frame with a 3/4" plywood top and a C-clamp it to the retractable step making a larger platform to step onto. I made the same configuration over one of those folding steel steps also making the platform area much larger...so you get the picture, you now have two larger platforms to step onto. I made a third one also that just sits on the ground as a third step. We love it, the dogs love it, so everyone's happy. (it does take up a bit of room to store though).
