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!

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 mocha accent crown molding over the kitchen cabinets!

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.

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.
