Load up your toys, gear, clothes and food to enjoy some off-road fun with your toys and friends! Once at the RV park, unload your toys, and setup the three slide outs, the two awnings, and begin planning your trail rides! You might decide to make a meal or snack in the combined kitchen and main living area which offers all the appliances you need, plus a kitchen island with extended countertop and two bar stools, a pantry, a 49" LED TV with a fireplace below, plus a slide out four-seat sofa. The garage even offers the option to add two Happi-Jac rollover sofas and a table with a top bed if you want seating and sleeping space, plus there is storage, a prepped space to add a washer/dryer option, and an optional half bath. The overhead loft bed provides sleeping space as well. You will love the sunken tub/shower with a seat in the full bathroom with a space savings sliding door, and the front bedroom can be your escape. There is a queen bed, a slide out wardrobe and USB charging outlets. If you want less garage space, take a look at 349M!

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!
