2023 Grand Design Momentum M-Class overview


The 2023 Grand Design Momentum M-Class series is a lightweight alternative within the company’s stable of 5th wheel Toy Haulers. Featuring many of the same features as the standard Momentum’s, the M-Class may be lighter in weight, which adds to the number of towable options, but it’s no lightweight when it comes to pampering its owner with luxury and off-grid capability. The M-Class offers 6 different floorplans, double or triple axles, and lengths from 38 feet to 44 feet, giving its owners a myriad of options to explore the great outdoors. Expansive garages built to accommodate all your toys are the focus, but the M-Class also has luxurious features in the other rooms that will make your stay enjoyable, no matter the location. Whether you are out in the desert for a race, staring up at the stars by the river, or skiing in the mountains, Momentum M-Class will provide you a comfortable home away from home.


Trade in your RVMomentim M-Class Floorplans


The 2023 Grand Design Momentum M-Class has a collection of 6 floorplans, giving owners multiple options to get out and explore in. The 336M is the newest addition to the M-Class family. It has a unique garage beneath the rear bedroom with over 200 cubic feet of space to use. The bed can even be raised up to provide more garage room. Alongside the garage is the fuel station, with 30-gallon capability. The bedroom also has multiple cabinets and drawers, and a nice flow to the bathroom. Step down to the kitchen and you will find a full-sized butler’s pantry, and island kitchen, and huge 18 cubic foot fridge. The front living room is just a step up away, and has two Tri-Fold couches, Theater-style seats, and a very cool telescoping TV that comes out of the fireplace. Next up is the 349M, which expands the garage to 13 feet in length. It also has the washer and dryer prep beneath the upper bunk bed, and an optional half bath is available as well. The dining room shakes things up with a large 4-person couch, from which you can see the large entertainment center. Also, the 349M is the first Momentum M-Class model to feature a sunken tub/shower in the bath, with a skylight giving over 6 feet of headroom. And finally, a 60-gallon gas station becomes standard from the 349M up. The 351MS moves the washer and dryer prep into the master bedroom, flanked by huge closets on either side of the front cap, and makes the half bath standard in the garage area. It also features a large, stainless-steel sink in the island, and seating for two at the countertop. The 381MS is the first Momentum M-Class to offer a 15 foot garage, adding more space for more toys to enjoy. The master bedroom also features a very interesting flip up cabinet that comes prepped for the high-definition television of your choice. The 395MS Momentum moves things around by separating the living room away from the kitchen, using two separate pullout sofas and theater seats to give a sense of privacy. Instead of an island, you have a very spacious L-shaped counter top and free-standing dinette to prep and enjoy your meals. And the 398M, the largest M-Class, offers all the previously mentioned amenities, plus an absolutely massive 18 foot garage, two full Happi-Jack bunks, and enough sleeping space for up to 8 people.

Door-side spray nozzles get your shoes clean before you track dirt into the inside. The mandatory Exterior package contains the All-in-One exterior Utility Center, which allows you to control all your water and flush tanks.

The entire underbelly of the Momentum is triple insulated, sealed and heated, protecting all pipes and water tanks, it even has 12v tank heaters. One of the newer additions is the front and rear under-unit blue LED lights. The glow from under the RV gives your campsite a unique look. The Rockford Fosgate speakers bring deep bass thanks to the 12 inch subwoofer and 300-watt amplifier, and are fully Bluetooth compatible. And the toy hauler specific fuel station, holding up to 60 gallons, allows you to carry all the fuel you need to keep your toys running.
