If you have little ones or guests, they can take the middle bunkroom with a hide-a-bed sofa and bunk bed above, and the desk in this room will allow you to make it into an office if you need. There is even a loft bunk above this room with a ladder for more sleeping or storage space! The main living area includes theater seating across from the entertainment center with a hidden pantry, and a second hide-a-bed sofa in this space can also be converted to sleeping space for tag-along campers. The chef will love the kitchen island for more counter space, a 12V refrigerator, plus an outside kitchen to enjoy the nice weather while they make dinner. 

 Each one of these Forest River Sierra fifth wheels are equipped with everything you need to make the most of each adventure! The underbelly armor will protect your unit's vitals from road debris and the painted two tone aerodynamic fiberglass front cap has an improved turning radius to make them easier to navigate. With an electric leveling system, you can set your unit up quick and easy then get to having fun faster than ever. The welded aluminum framed, vacuum bonded laminated superstructure will hold up through every adventure and the cambered powder coated frame comes with rust prohibitor to last longer. Each model also includes the Summit Package that comes with a king Wi-Fi extender system and Olympus antenna, a full coach water filter system, Goodyear tires with 7,000 lb. axles, and the list goes on. The interior is just as impressive with rustic wood plank linoleum, recessed residential lighting, a memory foam mattress, and accent crown molding over the kitchen cabinets!
