The 2026 Grand Design Momentum 395MT is a high-end luxury toy hauler fifth wheel designed for RVers who want garage capability, residential living comfort, and extended-season durability in one premium package. At approximately 46’4” in length with a dry weight around 19,100 lbs and a GVWR of 23,500 lbs, this model sits at the top of the Momentum lineup, offering serious hauling capacity alongside upscale living spaces built for full-time or extended travel use.
Inside, the 395MT is built around a highly functional 14-foot separate garage, giving you dedicated space for ATVs, motorcycles, side-by-sides, bikes, or extra storage. The garage also includes tie-down systems, a half bath, washer/dryer prep, and convertible sleeping options, making it usable as both a cargo area and a flexible secondary living space.
The main living area is designed like a modern luxury apartment, featuring a large lounge with theater seating, an L-shaped reclining sofa, and a hybrid desk/dinette setup for dining or remote work. A centrally located entertainment wall with a fireplace and LED TV creates a cozy focal point, while large windows help brighten the space and make it feel open even in a full-profile toy hauler.
The kitchen is built for real cooking on the road, offering a large residential-style refrigerator (up to ~20 cu. ft.), professional-grade cooktop, microwave, and solid-surface countertops, along with deep storage and pantry space for long trips. This makes it ideal for families or travelers who spend extended time away from home and don’t want to rely on campground dining.
Up front, the private master bedroom includes a queen bed slide (king optional), wardrobe storage, and washer/dryer prep, giving the front suite a true residential feel. The adjacent bathroom includes a large shower with seating, vanity, and porcelain toilet, designed for comfort after long travel or outdoor recreation days.
Built on Grand Design’s heavy-duty Momentum platform, the 395MT includes 101” wide-body construction, triple axles, laminated fiberglass walls, and a fully enclosed and heated underbelly, making it suitable for extended-season and four-season capable camping. Exterior features typically include multiple power awnings, a 6-point hydraulic leveling system, fuel station, and rugged suspension components, ensuring both campsite stability and off-grid capability.
