Go big, conveniently.

The 2021 Momentum G-Class is lighter without sacrificing any comfort or spaciousness — thanks to our tall ceilings and slide outs. With all of the quality, innovation, and functionality that our family of Momentum owners love, it's everything you need and nothing you don’t.

You don't have to rough it with all the amenities found in this Momentum G-Class toy hauler including your own master suite with a walk-around queen bed slide and private access into the dual-entry bathroom.  The kids or your friends can sleep on the Happi-Jac power bunk above the rollover sofas with table, and the Euro chairs can become the waiting area for the next rider while they visit with the cook who is making snacks. Keep the party going all weekend long with your very own fuel station and the Rockford Fosgate speakers. Come see why this model will fit perfectly into your off-road lifestyle! Are you looking for adventure and fun? The Momentum G-Class toy hauler by Grand Design will help you find it! You can explore during any season you choose with the Insulation Package that includes a heated and enclosed underbelly with suspended tanks, a high-capacity furnace, a moisture barrier floor enclosure, and cabinet-mounted heat ducts. Each model includes a 30-gallon fuel station with an interior and exterior gauge, a dovetail rear rend, and 2,500-LB tie-downs anchored into the chassis. Throughout the Momentum G-Class interior, you'll enjoy many comfortable features like large panoramic windows, a shower skylight, USB chargers in the bedroom, and residential cabinetry.
