The 2026 Grand Design Momentum G-Class 31G is a premium toy hauler travel trailer built to deliver a balance of cargo capacity, residential comfort, and off-grid capability. Measuring just under 36 feet with a dry weight around 9,000–9,700 lbs, it offers strong towing capability while maintaining a spacious dual-slide layout.

The defining feature is the 13-foot separate garage, designed to haul motorcycles, ATVs, or larger gear while doubling as a flexible living and sleeping space. The Happi-Jac system allows the garage to convert into seating and bunk beds, while the ramp door can be used for easy loading and optional patio setup.

Inside, two slide-outs expand the main living area, creating an open layout with theater seating and an entertainment center. The kitchen includes a three-burner range with oven, microwave, and an 8 cu. ft. refrigerator, along with residential-style cabinetry and solid-surface countertops for durability and function.

A standout feature of the 31G is the bath-and-a-half layout, providing added convenience for guests and families. The front private bedroom includes a queen bed, wardrobe storage, and direct access to the main bathroom, while the half bath is located in the garage area for easy access during outdoor use.

Built for extended trips, the 31G includes large holding tanks, a tankless water heater, and a high-capacity furnace. The heated and enclosed underbelly and insulation package allow for multi-season camping, while solar prep and optional solar upgrades support off-grid capability.

Exterior features include an 18-foot power awning, universal docking station, large storage compartments, and a 30-gallon fuel station to keep your toys ready for use.
