The 2024 Grand Design Momentum 381MS doesn t just check all the boxes it elevates what a toy hauler can be. From its intelligently configured living spaces to its rugged hauling capability, this is a trailer that feels like a true home on wheels the moment you step inside, yet it s built to haul hard and play harder.

Step into the spacious garage area and you ll immediately appreciate the thoughtful design: a massive 15-foot garage with premium tie-downs, modular seating, and a ramp-to-patio deck means your toys from ATVs to side-by-sides go in and out with ease. When the gear is unloaded, the same space quickly transitions into a second living zone, entertainment area, or extra sleeping quarters, giving you real flexibility on how you use every square inch.

Move forward into the main living area and the Momentum really shines. Dual opposing slides open up the interior, creating a wide-open great room that feels more like a luxury apartment than an RV. Plush theater seating and a comfortable sofa face a large entertainment center with fireplace perfect for cozy movie nights or relaxing after a long day. The panoramic windows bring in light and keep the space feeling bright and inviting.

The kitchen is built for real life not just camping. Solid-surface counters, a residential-style refrigerator, large cooktop and deep sink combine with abundant cabinetry ","itemCondition":"Used","priceCurrency":"USD","price":"95650.00"}}]}}
