There's a powerful 24-ft lobby, and a powerful 26-foot lobby, in Class C's. Thing about C's, is that cabover bunk. It creates a second sleeping area that many if not most Class A's don't have. We are a couple, and we're in a 31-ft that we've weighed. It's right at chassis max with just us and our habit of packing heavy. We have a lot of supplies, tools, food and clothing. Reducing to "necessities" a family of four could sleep two in the rear queen (smaller C's would be a rear corner) and two could sleep in the "loft" up front, leaving both the foldout sofa and the convertible dinette clear. Deploy both and sleeping capacity goes to eight. Leaves a passage between dinette and kitchen back to the bedroom, but cabover climbs down onto sofa bed, and there's just about no getting to the coach door to the outside. We have seatbelts for all eight, counting two in the cockpit.
Just for me, I don't want to be setting up sleeping area(s) every night and not being able to do anything in the morning till they've been folded up. But that's OK with many.
There are some modern designs that incorporate drop down beds in small Class A's, there's Thor's "ACE" for A-C Evolution that might work. Some smaller coaches now have bunk beds on one side.
Floor Plan Rules! If you can't live in it, then you can't enjoy it and that's when you won't use it.
