I'm not sure how big you want to go but I would consider the Grand Design 2400BH. We have the 2800BH and the 2400BH is the same floorplan minus the theatre seats/couch. The bunks are double bunks which is a plus for growing kids. We have a 16 year old that sleeps in one and she has plenty of room. They also have big tanks, 52 gallon fresh water, 39 gallon black, and 71 gallon grey (split between 2 grey tanks). Another plus is it has a residential size queen and 81 inch high radius ceiling. Grand Design also has one of the better reputations in the RV industry for customer service.
