Wade:
I seriously doubt that you will ever see a couch in the back, due to the overhang. I suspect that seating will usually stay in the front, near the center of gravity for passenger comfort. Now, a permanent bed is another matter. Br's 25' B+ has a bed in the back now. I believe his wheelbase is longer than mine (mine is 139"). I can turn it almost as sharply as my PT Cruiser! Anyway, I would anticipate that R Vision will start adding a slide in that model soon, and it will still be lighter than most of the other brands. If you are still a few years out from a decision, I can imagine there will be some neat additions by then! I suspect that there are some really good RV's available in Europe, since they have had to think smaller from the beginning.
