Virtual Tour
2021 397TH Features and Options
Grand Design Momentum toy hauler 397TH highlights:
  • Dual Entry
  • Two Full Baths
  • Kitchen Island
  • 12' 6" Separate Garage
  • Island with Bar Stools
  • Walk-In Closet

 

This Momentum toy hauler provides the maximum entertainment with its 49" LED TV in the living area, 32" LED TV in the private bedroom, 32" LED TV in the 12' 6" separate garage, and exterior LED TV! You can choose to add the optional Super Sofa which will create an amazingly comfortable area to sit down across from the electric fireplace. The two full bathrooms are one of the most impressive features found on this unit, and the three power awnings are another shocking addition. Within the kitchen, you'll be able to prepare all of your family's favorite dishes when you use the chef-inspired range and oven, and the window behind the range allows you to view the campsite while you cook. If you would prefer to have a residential refrigerator, you should check out model 397TH-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 Onan 5.5kW generator, Solitude solar system, and Rockford Fosgate speaker package.
