Adventure feels effortless in the NEW 2026 Grand Design Momentum 351MS, a fifth wheel toy hauler designed for riders, families, and groups who want to travel together without giving up comfort. From desert trails outside Tucson to extended off-grid stays, this Momentum delivers a smart balance of rugged capability and residential-style living.
The 11' separate garage is ready for your off-road toys and easily transforms into a versatile second living or dining space once you’re parked. An overhead loft bed adds extra sleeping capacity, making it easy to bring friends or family along for the ride. With dual entry doors and a rare bath and a half, traffic stays smooth at camp and everyone has convenient access whether you’re coming in from the trails or relaxing indoors.
The main living area is built for gathering and relaxing after a long day outdoors. A large super sofa offers comfortable seating and additional sleeping space, while the LED TV and fireplace create a cozy atmosphere on cooler desert evenings. The slide-out design opens up the floorplan, giving you room to stretch out and enjoy every moment at camp.
At the heart of the coach, the kitchen island with integrated sink and bar stools becomes the perfect hub for meals, snacks, and conversation. Upgraded appliances, generous counter space, and smart storage make it easy to cook for a crowd, whether it’s a quick breakfast before hitting the trails or dinner after sunset.
Up front, the private bedroom offers a true retreat. The queen bed slide, with an optional king bed, provides a comfortable night’s rest, while the slide-top dresser and abundant wardrobe storage keep clothing and gear organized for longer trips.
Momentum fifth wheel toy haulers by Grand Design are engineered for four-season adventure. Construction includes a fully enclosed and heated underbelly, five-sided aluminum cage, and triple insulated garage flo
