The Momentum M-Class 381M isn’t just a toy hauler—it’s your home base for adventure. With its four-season Weather-Tek insulation, you can extend your camping trips into every season, whether you’re chasing mountain trails in the summer or enjoying desert rides in the winter. The garage is engineered for durability with triple insulation, oil- and gas-resistant flooring, and plenty of tie-downs to keep everything secure on the road.

Inside, Grand Design spares no detail. Large windows flood the living area with natural light, while the kitchen island makes meal prep easy and social. The loft adds flexibility for sleeping or storage, and the master bedroom ensures restful nights so you’re ready to hit the trails again in the morning.

Luxury Meets Playtime
After a day of riding, hiking, or exploring, unwind in the spacious living room with the glow of the fireplace and a movie on the big screen. Share meals around the island or relax on the plush sofa seating. With both a full bath and a half bath, morning routines are smooth even with the whole crew onboard. The combination of practical features and luxurious touches makes this Momentum the ultimate toy hauler for those who want it all.
