2023 Grand Design Momentum 349MR

The Grand Design Momentum?349MR is a mid-size M-Class toy-hauler fifth wheel that balances cargo capacity and comfortable living. With a 13-foot garage, full house-style amenities, and generous water/storage capacity, it’s built to haul toys during the day and offer full living comfort at night — ideal for long weekends, extended trips or off-road adventures. Highlights Spacious garage + cargo capacity: 13-ft rear garage and robust cargo capabilities make it ideal for ATVs, motorcycles, tools or gear. Full-featured living space: Bedroom, full kitchen, bathroom, ample storage and residential-style utilities allow comfortable stays like a regular RV. Generous water and utility capacity: Large fresh, grey and black water tanks plus dual-LP setup support extended stays with minimal hookups. Flexible layout sleeping: Slideouts expand living space; multiple convertible areas offer flexibility depending on whether you’re hauling cargo or using for living. Balanced size towability: At ~13,600?lb dry weight, it remains towable by properly equipped ¾-ton or heavy-duty trucks but still gives good living + hauling capacity.
