Get ready for a lot of fun when you head out to the off-road park, a special event, or a long trip with your toys! You will love the garage with the Fast Ramp rear ramp door, the Ram-Air garage vents on both sides, the 2,500 lb. rated flush-mount tie-downs and the protective diamond plate on the garage sidewalls. This area can become a bedroom or an extra living area if you want to add Happi-Jac rollover sofas/table with a top bed option, plus you will already have a half bath for convenience, an overhead loft bed plus a flip-up pet dish for your furry friends. The living and kitchen area is spacious with dual slides and a kitchen island with bar stools, a free standing dinette and theatre seating. The fold-down side patio offers a great place to relax outdoors above ground, and there are many more features to enjoy plus several options to customize your fifth wheel.
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 thermal roof design, the full-laminated walls, 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, raised panel 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!
