NEW 2026 Grand Design Momentum 392M Fifth Wheel Toy Hauler

Adventure meets luxury in the New 2026 Grand Design Momentum 392M, a high-performance fifth wheel toy hauler designed for those who want to bring their toys—and their comforts—along for the ride. With a massive 17' separate garage, upscale residential finishes, and true four-season capability, this Momentum is built for extreme living without compromise.

The dedicated garage space is ready for action with an adjustable tie-down system, triple-insulated garage floor, two LiftSuite Systems, and an overhead loft bed for additional sleeping or storage. You’ll also appreciate washer and dryer prep, an optional half bath, and a flip-up pet dish, making this toy hauler as functional as it is pet-friendly. The ramp door converts to a patio, creating the ultimate outdoor hangout once the toys are unloaded.

Inside the main living area, dual opposing slides create an open, residential feel. Relax on the L-shaped reclining sofa across from the 50" TV, or take advantage of the hybrid desk/dinette for working on the road. The spacious kitchen is a standout, featuring expansive countertops, a 20 cu. ft. refrigerator, and a large pantry—perfect for extended trips or full-time use.

Up front, the private master bedroom offers a peaceful retreat with a queen bed (with optional king upgrade), a slide-out for added floor space, and ample drawers and storage to keep everything organized.

Built to handle rugged adventures and all-season travel, the Momentum 392M features a fully enclosed and heated underbelly, 5-sided aluminum cage, and Grand Design’s Weather-Tek Package with a Stealth A/C system. The MORryde CRE3000 suspension, rubber pin box, and upgraded axle hangers ensure confident towing and a smooth ride from pavement to trailhead. Inside, premium touches like solid surface countertops, hardwood cabinet doors with hidden hinges, color-changing LED accent lighting, and a central vacuum system elevate the experience.
