Queen Bed Slide Out
U-Shaped Kitchen Counter
Free-Standing Dinette
Kitchen Pantry
14' Separate Garage
Flip-Up Pet Dish

Any time spent in this spacious toy hauler will be time well spent! The 14' garage includes an overhead loft bed and a flip-up pet dish for your furry friends. If you're needing more sleeping space, you might want to choose the optional Liftsuite System and optional half bath. Once you enter in the main living area, you can relax on the L-shaped sofa with recline across from the fireplace, and there is a free-standing dinette if you want to play a game or two. The chef of your group will love the generous counter space in the kitchen, and the dual entry bath will let everyone stay clean throughout your trip! Head to the front master bedroom to enjoy the queen bed slide out with an optional king bed, a slide top dresser with TV prep, plus a large front closet, complete with washer and dryer prep!

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 a, 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.
