I suggest you visit this
almost 14 year old topic. A lot of ongoing discussions about the small B+ type motorhomes. Our
Trail-Lite Model 213, B-Plus, has a sofa across from the dinette which opens to a king size area, we use a queen air mattress as a topper. Plus I have PVC supports to keep flex out of the sofa back and a small sheet of 3/8" plywood under one of the dinette cushions to bridge a small gap between the two areas. We took the RV to Alaska in 2013 for a 79 day trip. It took 5-7 minutes to set up and tear down, including the air mattress and a sleep sack.
