2023 Grand Design Momentum M-Class 381MS

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”.

This 381MS is an even better version of the standard 381M we have all come to love.  New features include a bedroom bed slide, new his & hers closets, separated by either shelving or a Washer/Dryer setup and Dual access to the bathroom. For sale at Good Life RV in Des Moines, IA
