Kitchen Island with Bar Stools
-
Overhead Loft Bed
-
Universal Docking Station
Traveling with friends and family can be comfortable when you have a full double entry bathroom and a half bath available when camping and enjoying the trails on your off-road toys! You will have an 11' garage space that can become a second living/dining area. An overhead bed comes standard, along with a super sofa in the main living area where guests can sleep. Everyone can watch the LED TV when waiting for dinner and enjoy the fireplace on those chiller nights. The kitchen island offers a sink to wash dishes, extra counter space for serving meals and two stools to dine at. The cook will love all the upgraded appliances, and the space thanks to the slide. The front bedroom gives you a queen bed slide with a king bed option, lots of clothing space, and a slide top dresser for even more storage.
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 independent suspension 2.0 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!
