Enjoy a home on wheels with this fifth wheel! There are two bedrooms to choose from plus an upper loft with two 32" x 74" bunk mats, cabinets, and TV prep. The front private bedroom has a queen bed slide across from a dresser and next to a front wardrobe that is prepped to add an optional washer and dryer. The second bedroom has a queen bed slide across from a dresser with wardrobes on either side, plus it's very own full rear bathroom which has a tub and a rear entry/exit door to the unit. The second full bathroom has a one-piece fiberglass shower so everyone can get ready quickly in the morning. Prepare your best home cooked meals with the kitchen island and three burner cooktop then enjoy it at the free-standing dinette. Relax in true comfort each night in the theater seating across from the fireplace and 50" TV at the entertainment center!
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 cambered powder coated frame with rust prohibitor construction allows for more duration of the fifth wheel. Each model also comes with a TV antenna with booster, 60,000BTU on demand tankless water heater, Goodyear Radial tires with 7,000 lb. axles, and the list goes on. The interior is just as impressive with Beachside Sundance Congoleum linoleum, recessed residential lighting, a memory foam mattress, and hidden hinged, soft close drawers and cabinets!
