As I indicated on a previous post, I would look at the Damon/Thor Outlaw toy hauler. It has sleeping in dinette and a couch as well as queen in loft area. The large toy hauler area is perfect for at least two sets of bunks. You could hang them from the wall so they fold up or build permanent bunks. With the height you could easily have tri-bunks on both sides for six sleeping so they can bring some friends and the space has an outside door and door to the main area. It is a gas motorhome so if they is a deal breaker then disregard.
