The 2026 Grand Design Momentum G-Class 320G is a premium mid-profile toy hauler fifth wheel built for riders, campers, and adventure seekers who want a perfect balance of garage utility, residential comfort, and towable size. At approximately 35 feet in length, this model delivers Grand Design’s signature quality with a functional rear garage + luxury living layout, making it ideal for ATVs, dirt bikes, e-bikes, or weekend adventure gear.

The standout feature of the 320G is its rear ramp-door garage system, which converts into a multi-use space for hauling toys during travel and transforming into additional living or sleeping space when parked. The garage includes convertible Happi-Jac power beds and sofa seating, allowing it to function as a lounge, sleeping area, or full cargo bay depending on your needs.

Inside, the main living area is designed with an open-concept feel, featuring theater seating, a tri-fold sofa, and a large entertainment center with a smart TV and optional fireplace, creating a comfortable residential-style lounge space. Large windows and opposing slide-outs (depending on configuration) help expand interior space and enhance natural light.

The kitchen is built for extended travel comfort, offering a residential-style refrigerator, three-burner cooktop with oven, microwave, solid surface countertops, and a large pantry, giving you everything needed for long weekends or full-season camping. Thoughtful cabinetry and storage solutions keep gear and food organized even when traveling with toys.

At the front of the unit, the private master bedroom features a walk-around queen or optional king bed, wardrobe storage, and overhead cabinetry. The adjacent bathroom includes a walk-in shower, vanity, and toilet, providing residential convenience in a durable, towable toy hauler platform.
