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 an optional 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. 

 

With any Momentum M-Class toy hauler by Grand Design, you will enjoy luxury at every turn! They have been constructed to a superior standard with a thermal roof design, triple insulated main floor and garage floor, and a Rail-Tite underbelly seal that will allow you to camp in all elements. Each model also features an 8' 5" wide body chassis with a wide rail design, no wheel wheels, and a dovetail entry for easier loading. The Stealth A/C system provides maximum cooling power, and the CRE3000 suspension system means you can enjoy a smooth tow each time. You will love the luxurious interior with a professional grade stainless steel cooktop, interior color changing LED accent lighting, a fiberglass shower with a glass door, and solid surface countertops.
