Forest River Sierra fifth wheel 3710HBFB highlights:

Front Bunkhouse
Bath and a Half
King Bed
Rear Bathroom

This Sierra fifth wheel is thoughtfully designed for comfort and convenience, starting with a spacious front bunkhouse perfect for accommodating guests. It features two flip-up bunks, 28" x 74" and 32" x 74" and a 60" x 74" fold-out lounge, along with a wardrobe, dresser, and additional storage to keep essentials organized. A nearby half bath adds easy access and extra convenience. At the center of the unit, the kitchen offers everything you need to prepare meals, including a stainless-steel sink, three-burner cooktop, and a generous 16 cu. ft. refrigerator. Meals can be enjoyed at the free-standing dinette, or you can unwind on the sectional sofa while enjoying the fireplace or entertainment center. At the rear, you'll find the private main bedroom with a roomy 66" x 80" RV king bed, plus its own wardrobe and dresser. Just steps away is the full bathroom featuring a one-piece fiberglass shower, sink with medicine cabinet, linen storage, and even washer/dryer prep for extended stays.

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!
