Adventure-Ready Design in the Momentum G-Class 320G Toy Hauler

The Grand Design Momentum G-Class 320G is built for travelers who want to bring all their toys along without sacrificing residential comfort. The 11-foot separate garage provides ample space for ATVs, motorcycles, or dirt bikes, and once unloaded, it easily transforms into additional living or sleeping space.

Inside, this toy hauler is designed for relaxation after a long day on the trails. The separate living area features a cozy fireplace, theater seating in a slide-out, and a full kitchen equipped for longer adventures. A loft bed adds an extra sleeping option, while the bath and a half layout provides exceptional convenience for groups or families.

The private front bedroom offers a quiet place to unwind and recharge, making it easy to enjoy early mornings or late nights at your favorite destination.
