The 2026 Grand Design Momentum G-Class 320G is a fifth wheel toy hauler designed to deliver high-capacity hauling with residential-style comfort. At just over 36 feet in length and built on a wide-body chassis, it provides a spacious triple-slide layout while maintaining a manageable footprint for experienced fifth wheel owners.
The rear 11-foot garage is built for versatility, allowing you to transport motorcycles, ATVs, or gear while converting into a living and sleeping area once unloaded. The ramp door doubles as a patio, expanding usable outdoor space and enhancing campsite functionality.
Inside, three slide-outs open up the main living area, featuring theater seating, a fireplace, and large panoramic windows. The kitchen is fully equipped with a 3-burner range, oven, microwave, and a residential-size 15 cu. ft. refrigerator, making it ideal for extended stays and full meal prep.
A key highlight is the bath-and-a-half layout, providing added convenience for families and guests. The front private bedroom includes a queen bed with storage, while additional sleeping comes from the loft and garage conversion system, increasing overall capacity.
Built for extended travel, the 320G features oversized holding tanks, a 30-gallon fuel station, and solar prep for off-grid capability. The heated and enclosed underbelly with high insulation ratings supports four-season camping, while the 35,000 BTU furnace and 30,000 BTU A/C maintain interior comfort in varying climates.
The heavy-duty construction includes an aluminum cage frame, MORryde suspension, and 8,000 lb axles, providing durability and stability for long-distance towing and frequent use.
