So many ways to live in one of these critters. I'm very partial to my 2008 Vista Mini 4230 on the sprinter chassis (diesel, 25ft, 15+ mpg) but that's just me. Boondocks for 4 days easy.
So my recommendation is look at floor plans to see what excites you and falls within your budget. Shop, shop, search, research and then do it some more. Don't limit your area searching either. I saved close to 20k simply by flying to the dealer and driving the rig home. Of course I also had two other dealers in the same area with similar rigs in case I needed a backup plan - I didn't, the dealer I worked with (Pedata in Tucson) even paid my airfare.
