Hi, We have a Trail Cruiser RBH21 by RVision. For its size it provides a large U shaped dinette(bigger than the 60x80" foam topper I bought) a rear 60x80(they may have narrowed it by3-4" for the newer models) and a single bunk over it for a child.This model came in the hard side which we have and one that had fold out beds like the beds on a pop up. It's light, GW under 5,000 lbs., and it was relatively inexpensive ($11,000 new). There are may choices from this inexpensive one to Airstreams at $30000+.
We bought this one to see if we enjoyed RVing. WE LOVE IT! But the TT is too small for us for more than 8-10 days. We are looking at a 5er now so we don't disturb each other because our sleep patterns are no longer the same.(called getting old)
