New 2026 Grand Design Momentum G-Class 350G Toy Hauler Fifth Wheel

The 2026 Grand Design Momentum G-Class 350G is a large fifth wheel toy hauler designed for maximum cargo capacity, residential living space, and extended travel capability. At just under 40 feet in length with a dry weight around 12,900–13,400 lbs, it offers a wide-body design and triple slide-outs that create a spacious, open interior.

The rear 14’6” garage is one of the largest in the G-Class lineup, built to haul motorcycles, ATVs, or larger equipment. Once unloaded, the garage converts into a multi-use space with a Happi-Jac bed system, seating, loft sleeping area, and a convenient half bath. The ramp door also functions as a patio, expanding outdoor living space.

Inside, three slide-outs open up the main living area, featuring theater seating, a fireplace, and large windows for natural light. The kitchen is fully equipped with a residential 15 cu. ft. refrigerator, three-burner range with oven, microwave, and solid-surface countertops, allowing for full meal preparation during extended trips.

The front private bedroom includes a queen bed with wardrobe slide and storage, while the main bathroom offers a large residential-style shower. The bath-and-a-half layout improves usability for families or guests, especially when using the garage and patio areas.

Built for long-term and off-grid use, the 350G features oversized holding tanks, a 30-gallon fuel station, solar prep, and a tankless water heater. The heated and enclosed underbelly, high R-value insulation, and 35,000 BTU furnace provide four-season capability, while dual A/C systems maintain comfort in warmer climates.

Heavy-duty construction includes an aluminum cage frame, MORryde CRE3000 suspension, and 8,000 lb axles, delivering durability and stability for hauling and long-distance towing.
