Experience the perfect blend of rugged adventure and residential comfort with the all-new 2026 Grand Design Momentum G-Class 320G. Built for thrill-seekers who refuse to compromise on luxury, this premium toy hauler fifth wheel is designed to take you farther, stay longer, and enjoy every moment in style. Whether you're hauling ATVs, motorcycles, or simply bringing along everything you need for extended travel, the 320G delivers power, space, and sophistication in one impressive package.

From the moment you arrive, the Momentum G-Class 320G stands out with its bold exterior, durable construction, and industry-leading insulation package—perfect for year-round camping. The spacious garage area easily converts into a versatile living space, complete with opposing sofas, a removable table, and an optional Happi-Jac bed system, making it ideal for guests or family. Tie-downs are strategically placed for secure transport, and the rear ramp door doubles as a patio deck, expanding your outdoor living space instantly.

Step inside and you’ll find a beautifully appointed interior that feels more like a high-end condo than a toy hauler. The main living area features theater seating positioned perfectly across from an entertainment center with a large LED TV and fireplace, creating a cozy atmosphere after a day of adventure. The kitchen is a true highlight, offering solid surface countertops, stainless steel appliances, a large residential refrigerator, and ample storage—perfect for preparing meals on the road.

Upstairs, the private master suite provides a relaxing retreat with a queen bed, generous wardrobe space, and washer/dryer prep for extended trips. The bathroom is equally impressive, featuring a spacious shower with skylight, modern fixtures, and plenty of room to move comfortably.

Performance is where the Momentum G-Class truly shines. With its heavy-duty frame, MORryde CRE3000 suspension system, and high-capacity axles, this fifth wheel is built for smooth towing and long-lasting durability. The fuel station ensures your toys are always ready to go, while the onboard generator prep gives you the freedom to camp off-grid with confidence.
