This toy hauler with a 17' separate garage will be perfect for your outdoor adventures. There is an adjustable tie-down system to keep your gear secure, an overhead loft bed, plus an optional half bath. And two optional Liftsuite Systems can be added if you need more sleeping space. There is also washer and dryer prep here, along with a flip-up pet dish for your furry friends. The chef will love the large kitchen countertop for more meal prep space, and there is a 20 cu. ft. refrigerator and pantry for food storage. You can get comfy on the L-shaped sofa across from the 50" TV, or get some work done at the hybrid desk/dinette. There are also dual opposing slides here for added space. The third slide out is found in the front master bedroom, which includes drawers and storage space for your things. A queen bed will provide a great night's rest, and you have the option to choose a king bed if you want more space to stretch out!
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.
