2018 Grand Design MOMENTUM 399TH, Extraordinary Living. Extreme Play.
The Momentum Fifth Wheel Toy Hauler is the point where absolute luxury meets mobile garage! We have completely raised the Toy Hauler bar by incorporating an elegant Master Bath and Master Suite (with full walk-in closet) into this unit! But trust us, we didn't ignore the Living and Garage areas. Check out our 360° tours and get a feel for the extraordinary space we've created.
