Grand Design's Momentum 399TH is a toy hauler that doesn't feel like one once you're inside. The side patio creates an outdoor living area that's genuinely usable, not just a bonus feature, and the apartment-like interior backs that up with a kitchen island, bar seating, and a north/south bed in the front bedroom. The 13-foot garage handles serious gear, and the R40 triple-insulated floor means it's built for more than fair-weather camping. Bath and a half keeps things practical when you've got a full crew, and Grand Design's reputation for fit and finish shows throughout.

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 a full walk-in closet) into this unit! But trust us, we didn't ignore the Living and Garage areas. Check out our Floorplan Fly-Through Videos and get a feel for the extraordinary space we've created. We know you will agree with us when we say that "The Momentum RV is the place to live well and play hard!". Our new Momentum M-CLASS Fifth Wheel Toy Haulers are lighter but are no lightweights when it comes to features. Inside and out, the Grand Design M-CLASS series has redefined the look and feel of the toy hauler. When it comes to elegant design and amenities, one word encapsulates it... “CLASS”.
