Description
Grand Design Momentum toy hauler 399TH highlights:
- Dual Entry
- Full and Half Bath
- Exterior LED TV
- 13' Separate Garage
- Loft
- Fold-Down Side Patio
If you are ready to play with your off-road toys, then it's time to hitch up this Momentum fifth wheel toy hauler after loading your toys in the 13' separate garage. You will be able to get cleaned up after getting muddy from the trails in the half bath in the garage or the sunken tub with skylight in the full bathroom up in the master suite. The kids can sit at the kitchen island with bar stools or relax on the theater seats while watching the 49" LED TV and fireplace. The fold-down side patio is going to be your favorite spot when summertime rolls around, and the exterior unobstructed pass-through storage compartment will allow you to bring along some lawn chairs that you can set up on the patio.
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!
