2023 Grand Design Momentum 21G

The all new Momentum G-Class is lighter without sacrificing any comfort or spaciousness — thanks to our tall ceilings and slide outs. With all of the quality, innovation, and functionality that our family of Momentum owners love, it’s everything you need and nothing you don’t.

In the Momentum 21G you can have the time of your life without missing out on comfort and luxury. Take advantage of amazing hauling capabilities, plus comfortable living quarters for cooking, relaxing, and more. When your toys are in the 14′ garage, everything tucks away – but when it’s out and about, you have multiple sleeping and lounge options.
