Designed for riders who want space, comfort, and true four-season capability, the NEW 2026 Grand Design Momentum 351MS delivers an ideal balance of rugged toy hauler performance and residential-style living. Whether you’re traveling with family or a group of friends, this Momentum makes every adventure more comfortable and more memorable.

The 11' separate garage gives you the flexibility to haul your off-road toys while also transforming into a second living or dining area once you’re parked. An overhead loft bed adds valuable sleeping space, making it easy to accommodate guests without sacrificing comfort in the main living area. Dual entry doors provide convenient access, and the bath and a half layout ensures everyone has room to get ready without waiting in line.

Inside, the main living space is designed for relaxation after a day on the trails. The super sofa offers sleeping space for guests, while the LED TV and fireplace create a warm, inviting atmosphere on cooler evenings. The kitchen is both functional and social, featuring a center island with a sink and bar stools, generous counter space, and upgraded appliances that make meal prep easy whether you’re cooking for two or the whole group.

The front private bedroom serves as a true retreat, offering a queen bed slide with an optional king upgrade, ample wardrobe storage, and a slide-top dresser for added organization. Throughout the coach, smart storage solutions and thoughtful design details make extended stays simple and comfortable.

Momentum fifth wheel toy haulers by Grand Design are engineered for extreme living and year-round travel. Construction includes a fully enclosed and heated underbelly, 5-sided aluminum cage, and a triple insulated garage floor. The MORryde CRE3000 suspension system, rubber pin box, and upgraded axle hangers deliver confident towing and a smoother ride. Inside, you’ll enjoy upscale finishes such as color-changing LED accent lighting, hardwood cabinet doors with hidden hinges, a central vacuum system, and solid surface countertops. Multiple factory packages—including the Garage Package, Weather-Tek Package with Stealth A/C, and Interior Luxury Package—ensure this Momentum is ready for wherever the road leads.
