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.
