    Grand Design Momentum M-Class 351MS Highlights:

    11' Garage
    Bath and a Half
    Loft Bed
    King Bed Suite
    Happi-Jac Bed System

    The Grand Design Momentum M-Class 351MS combines luxury fifth-wheel living with the versatility of a toy hauler, making it an excellent choice for adventure seekers and extended travelers alike. The 11-foot garage provides dedicated space for motorcycles, ATVs, golf carts, or other gear while also serving as a flexible guest suite with a Happi-Jac rollover sofa system, overhead bed, loft, and convenient half bath. In the main living area, opposing slides create an open residential feel with comfortable seating, a large entertainment center, and a fully equipped kitchen featuring a residential refrigerator, three-burner cooktop, microwave, pantry storage, and generous counter space for meal preparation. The thoughtful layout offers plenty of room for relaxing, entertaining, or spending time with family after a day of adventure.

    The front portion of the coach is designed for comfort and convenience with a spacious bathroom featuring a sunken shower with skylight, linen storage, and residential-style amenities. The private master suite includes a king bed, large wardrobe storage, dresser, and washer/dryer for extended stays on the road. Outside, the large power awning creates a comfortable outdoor living space, while substantial tank capacities and toy-hauler functionality make this coach ideal for off-grid camping and longer trips. With its versatile garage, luxury residential interior, king bedroom suite, and premium amenities throughout, the Momentum M-Class 351MS delivers an exceptional blend of comfort, storage, and adventure-ready capability.
