Recommendation for New or Used Bumper Pull Toy Hauler

my brother and his family have an Attitude. It's an open floor plan meaning no separate garage. It's a shorter fiver model and they really like it except I'm not sure they can get a 4 seat SxS in there. Has swivel rockers and a big bay window. They're the second owners & have owned it for 5 years. Mostly use it in Forest Service campgrounds and boondocking.
