2022 399TH Features and Options
Grand Design Momentum toy hauler 399TH highlights:
  • Dual Entry
  • Full and Half Bath
  • Exterior LED TV
  • 13' Separate Garage
  • Loft
  • Fold-Down Side Patio

 

Whatever your idea of adventure is, this Momentum toy hauler will make it even better! The fold-down side patio is the perfect party space, especially since there is also an exterior LED TV, and back on the interior, you'll find three more LED TVs for entertainment while staying indoors. The front master suite is going to provide you with the most comfort while you sleep, and the electric fireplace within the main living area is going to provide you with an extra bit of heat on chilly nights. The kitchen has an island with bar stools so that you can sit down and chat with the chef, and you can also choose to sit back in the theater seating with heat/massage to relax after a long day of biking or hiking. If you would prefer to have a residential refrigerator, you should check out model 399TH-R!

 

The very best adventures are waiting for you with the Grand Design Momentum toy hauler! The Momentum combines extreme play with extraordinary living so that you can have the best of both worlds. You won't have to miss out on any of your favorite features from home because the Momentum has just about everything. With the Weather-Tek insulation, you won't have to let anything hold you back from getting out and taking an adventure during any season, and the Tuff Ply gas-and-oil-resistant garage flooring is a quality base for your toys. The flush-mount tie-downs rated for 2,500 LBS will keep your gear in place as you travel, and there is a protective diamond plate on the garage sidewalls for additional protection. Some of the options that you can choose to add to your Momentum are the Solitude solar system and Rockford Fosgate speaker package.
