If your off-road toys have been calling your name, hitch up this Momentum fifth wheel toy hauler after loading your toys in the 12' 6" garage and head out to the campground. You will be able to clean up after getting muddy from the trails in the full bathroom in the garage or the second full bath next to the front private bedroom. The kids can sit on the bar stools at the kitchen island while you cook or relax in the theater seats while watching the 49" LED TV and fireplace. There are several options to choose from and many more features to enjoy such as the two entry doors, the loft, and the exterior unobstructed pass-through storage compartment!

 

With any Grand Design Momentum toy hauler fifth wheel, you will enjoy extraordinary living and extreme playtime with the Weather-Tek insulation for four seasons of protection and a fully enclosed fuel pump station to keep the fun going the whole time. The Tuff-Ply garage flooring is gas and oil resistant, and it includes 2,500-LB flush-mount tie-downs to keep your toys secure while moving down the road. The interior includes color-changing LED accent lighting, a convection microwave, a central vacuum system with tools and a dust pan, and a OneControl 7" touchscreen control panel with app controls so that you can operate many of your RV's functions from wherever you want. Any Grand Design Momentum allows you to keep your active lifestyle no matter where you decide to stay!
