Well, I tried my standard-size wheelchair on the lower floor of my fifth wheel and found that I can use it. Of course, it has to be folded to get through the entry door, but with the help of friends it's doable. I'm going to continue getting physical therapy and hopefully in the near future be able to get back to my RV. Paying almost $3k/month at this facility is getting a bit old, although I had no choice at the time. :(
