New 2026 Grand Design Momentum M-Class 381MS

The New 2026 Grand Design Momentum M-Class 381MS is built for RVers who want the ultimate combination of luxury living and serious toy hauling capability. Featuring a spacious 15-foot garage, this floorplan is perfect for hauling motorcycles, ATVs, side-by-sides, or outdoor gear while still delivering a high-end residential feel. The garage easily converts into a versatile living and sleeping space with rollover sofas, a HappiJac bed system, and a loft above, making it ideal for guests or additional family members.

The main living area offers a wide-open layout thanks to multiple slide-outs, creating a true residential environment. Comfortable theater seating and a large sofa face the entertainment center and fireplace, while the kitchen is designed for real cooking on the road with a large kitchen island, residential refrigerator, cooktop, oven, microwave, and generous cabinetry. One of the standout features is the bath and a half, providing added convenience for families or guests, especially with the half bath located near the garage area.

Toward the front, the private master suite delivers a relaxing retreat with a king bed, wardrobe storage, and dresser space. The main bathroom includes a spacious residential-style shower and vanity, giving you all the comforts of home while traveling. Outside, dual power awnings and large exterior storage compartments create the perfect setup for relaxing, entertaining, and enjoying time at the campsite.
