Make the most out of every adventure with a Forest River Sierra fifth wheel! With unique models like bunkhouses, front living areas, and mid-bunk/office rooms, you can be sure to find one that best fits your needs.
The electric leveling system included makes setting up a breeze allowing you to start having fun sooner. The underbelly armor will protect your unit's vitals from road debris and the painted two-tone aerodynamic fiberglass front cap with improved turning radius will make it easier to maneuver. You'll also enjoy the on demand tankless water heater, floor ducted 35,000BTU furnace, and more amenities to make camping hassle-free. And the cook in your group will love the Chef collection stainless steel four-burner range, complete with solid surface countertops, decorative backsplash, and a spacious 12V refrigerator to name a few features.
Come see how the Forest River Sierra fifth wheels have the perfect balance of size, space, features, and luxury!

Customer Satisfaction is Our #1 Priority.
At Forest River, Inc., your needs, interests, budget, and lifestyle are at the forefront of everything we do. This affects every step from design, to the manufacturing floor, and on to you, our Customer. Whatever your need—recreation, transportation, or cargo hauling—we strive to bring quality products within reach of everyone. It’s not just a slogan: “Customer Satisfaction is Our #1 Priority.”
In 1996, Forest River founder Peter Liegl had a vision. He foresaw an RV company dedicated to helping people experience the joy of the outdoors by building better recreational vehicles. After purchasing certain assets of Cobra Industries, the Company started manufacturing pop-up tent campers, travel trailers, fifth wheels and park models. Continually growing, Forest River now operates multiple manufacturing facilities throughout the United States producing Class A, B and C motorhomes, travel trailers, fifth wheels, toy haulers, pop-up tent campers, truck campers, park model trailers, destination trailers, cargo trailers, commercial vehicles, buses, pontoons, and mobile restroom trailers.
Our large production capacity enables us to fill our customers' orders promptly without cutting corners or rushing through production procedures. This ensures that each Forest River product is conscientiously built and undergoes thorough, detailed inspection before it's shipped to the customer. This guarantees that every family who desires quality recreation will find a Forest River product that serves their needs, interests, budget, and lifestyle.
