Spend your days at the campground kicking up mud with this toy hauler in tow! once you've unloaded your toys from the ramp door, you can use the 60 gallon fuel station to fill up and head out on a trail! The overhead bed provides a place for guests to sleep, and there is a Liftsuite System for more sleeping space if needed. There is even an optional half bath here if you choose to make this space more accommodating. Head to the middle kitchen and living area where you'll enjoy generous counter space to prep meals, a spacious 20 cu. ft. refrigerator, an L-shaped sofa with recline, plus a hybrid desk/dinette that will serve as a dining or working space. The dual entry bath creates a front master bedroom you are sure to love. There is a queen bed with an optional king bed, plenty of overhead storage, and a wardrobe slide to keep your things organized.

The Momentum fifth wheel toy haulers by Grand Design are built for four seasons of travel with your off-road toys and include luxurious accommodations throughout for extreme living! Each is constructed to a superior standard with the fully enclosed and heated underbelly and storage area, the 5-sided aluminum cage, and the triple insulated garage floor. The MORryde CRE3000 suspension system and rubber pin box, plus the upgraded axle hangers provide the performance and smooth towing you desire, while the interior offers luxury such as color changing LED accent lighting, hardwood cabinet doors with hidden hinges, and a central vacuum system. Each toy hauler also includes four packages, including the Garage Package with Tuff-Ply gas and oil-resistant flooring, the Weather-Tek Package with a Stealth AC System, and the Interior Luxury Package with solid surface countertops!
