2026 394G Features and Options

The 2026 Grand Design Momentum G-Class 394G is a flagship fifth wheel toy hauler designed for maximum space, cargo capacity, and residential comfort. At nearly 45 feet long with a wide-body chassis and triple slide-outs, it delivers one of the largest interiors in the G-Class lineup while maintaining a functional, adventure-ready design.

The 15-foot separate garage is built to handle large toys such as side-by-sides, motorcycles, or multiple ATVs. Once unloaded, the space converts into a flexible living area with a Happi-Jac bed system, seating, loft, and a convenient half bath. The rear ramp door transforms into a patio, expanding outdoor living space and usability at camp.

Inside, three slide-outs create a wide, open main living area featuring an L-shaped sofa, theater seating, fireplace, and entertainment center. The kitchen includes a residential 15 cu. ft. refrigerator, three-burner range with oven, microwave, and solid-surface countertops, supporting full meal prep for extended trips.

The front private bedroom provides a queen bed with wardrobe storage and washer/dryer prep, while the main bathroom features a large walk-in shower. The bath-and-a-half layout improves convenience for families and guests, especially when using the garage and patio areas.

Built for long-term travel, the 394G includes oversized holding tanks, a 30-gallon fuel station, and solar prep for off-grid capability. The heated and enclosed underbelly with high insulation ratings (R-40 roof/floor) supports four-season camping, while the 35,000 BTU furnace and multiple A/C options maintain comfort in varying climates.

Heavy-duty construction includes a triple-axle setup, aluminum cage frame, and high-capacity suspension, delivering stability and durability for hauling and long-distance towing.

What Our Customers Are Saying

Fantastic service and support!

Fantastic service and support. Jim and Mike know RVs and even more important know the industry and all the conditions that are affecting RV sales. In addition, RV Kountry went above any beyond when it comes to the sale of my coach. They coordinated battery replacements and other repairs. I would highly recommend RV Kountry. Thanks for all your help. - Greg
