A Floorplan With Room for Everyone At approximately 39'6" in length, the 3712RDMB opens up with quad slide-outs to create a genuinely spacious living area once you're parked. A dedicated loft accessed by ladder near the main entry gives kids their own space that's just for them, while a separate room off the main living area doubles as a kids' bunk space or a private guest room, complete with a sofa that converts to an extra bed for overflow sleeping. In the master bedroom, you get a standard queen bed with slide-out nightstands (a king upgrade was also available on this floorplan), giving the primary sleeping area a real bedroom feel rather than a cramped afterthought. The kitchen and living area are built around a large flat-screen TV setup, making it a natural gathering spot for movie nights or catching the game after a day at the campsite.
