The fully equipped kitchen includes a flip-up countertop extension, giving you extra prep space for meals, plus a large 15 cu. ft. refrigerator to keep food and drinks ready for longer trips. A convenient flip-up pet dish makes traveling with four-legged companions easy and comfortable.

Freshen up in the full bathroom with a walk-in shower, complete with a skylight that brings in natural light and added headroom. When it’s time to unwind, the front private bedroom offers a quiet retreat with a comfortable queen bed and storage to keep your gear organized for the next adventure.

Momentum G-Class toy haulers by Grand Design are engineered for year-round exploration. The Insulation Package includes a heated and enclosed underbelly with suspended tanks, a high-capacity furnace, moisture barrier floor enclosure, and cabinet-mounted heat ducts, so you can camp confidently in changing conditions. Additional features like a high-capacity water pump, dovetail rear end, and 2,500 lb. tie-downs make this model as capable as it is comfortable.
