You’ll enjoy every adventure in this Sierra fifth wheel, designed for couples who love to hit the road and make the most of every getaway. This Sierra features triple slides for added space, a large kitchen island, plus a free-standing dinette in the kitchen area which makes it feel a lot like home. When outside, you can enjoy being seated under the two power awnings with an LED light strip which is great for evening entertaining or relaxing. When it's time to get cleaned up and ready for bed, you will appreciate the spacious bath with a one-piece fiberglass shower, a linen cabinet, and sink with a medicine cabinet as well. A front private bedroom with king bed slide will provide you with a great night's rest, and the large wardrobe has shelves for all your things. This model even has washer/dryer prep that will allow you to add a washer and dryer to make full-time easier than ever!

 

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!
