Description

Grand Design Momentum M-Class toy hauler 351MS highlights:

Bath and a Half
11' Separate Garage
Dual Entry Doors
Kitchen Island w/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 as well as a bedroom if you decide to add the Happi-Jac rollover sofas and a table with a top bed option, plus you can add other options such as an LED TV and/or a washer/dryer. There is an overhead loft bed and a four-seat sofa slide for more sleeping space in the main living area. Everyone can watch the 49" 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 or choose a king, lots of clothing space, and a flip-up dresser for even more storage. If you want more garage space, take a look at 381MS!

The Momentum M-Class fifth wheel toy haulers by Grand Design are lighter than the Momentum yet aren't lightweight on features when it comes to elegant design, luxury and a "Class" of its own! The chef-inspired kitchen provides a free-standing 3.7 cu. ft. gas range, a four burner cooktop with cast iron grill, an electronic ignition oven, and a digital display and interior oven light, plus 42,500 BTU of cooking power. The upgraded main bathroom offers solid surface counter tops, a three-jet shower panel system, a shower wand, and a teak bench seat. Each toy hauler includes a triple insulated garage floor, Tuff-Ply gas and oil resistant garage flooring, 2,500 lb. rated flush-mount tie-downs, and a Fast Ramp rear ramp door with two-sided lift-assist technology making it easy for one person to operate. And the MORryde CRE3000 suspension system and the rubber pin box, plus the upgraded axle hangers provide performance and smooth towing to your favorite destinations!
