The 2023 Grand Design Momentum G-Class 31G is a well-equipped toy hauler travel trailer designed for adventurers who want both rugged capability and comfortable living space on the road. At just under 36 feet long with dual slide-outs and robust construction, this model offers a thoughtful balance between functional garage space and residential comfort, making it ideal for weekend warriors and long-distance explorers alike.
One of the standout features of the 31G is its 13-foot separate garage area, which provides plenty of space for dirt bikes, ATVs, kayaks, or other gear — complete with secure 2,500-lb tie-downs and a built-in 30-gallon fuel station with both interior and exterior gauges. This space doubles as a flexible living or hangout zone thanks to optional Happi-Jac sofas and convenient access to the half bathroom in the garage, so guests don’t have to track mud through the main living area.
Inside, the Momentum 31G blends adventure-ready features with creature comforts. The main living area includes slide-out theater seating and an LED HDTV, while the kitchen is outfitted with appliances and cabinetry designed for extended stays. The bedroom forward of the living area offers a private retreat with easy access to the full bathroom. Large panoramic windows and thoughtful interior touches like USB charging ports and a shower skylight enhance the sense of openness and utility.
Built with a focus on durability and year-round use, the 31G includes an insulation package with a heated, enclosed underbelly, suspended tanks, and cabinet-mounted heat ducts, enabling comfortable camping even in cooler conditions. Exterior amenities such as a power awning with LED lighting, solar prep, and premium audio add to its appeal for outdoor living. Overall, the 2023 Momentum G-Class 31G is aimed at RVers who want a capable toy hauler with residential-style comfort and thoughtful design.
