B+rvwannabe, since I couldn't sell you a new $100k class B, how about a used Rialta (class A or C, depending on who is arguing, but for all intents and purposes, the quintessential B+). They cost $55k when new about 2 years back when still available, and one floorplan had rear twins. It is a sleek design based on a VW front end. It has front swivels and even a dry bath (there was a pull out door to create the room, and a removable floor panel that creates a shower water catch.
It is the separate room twins that keep me from matching you to a B+, where twins are in the center of things. If course, Born Free President on a Super C has a twin bed option, but it is longer and more money than you want.
