The 15-foot garage is the headline here. Large enough to haul serious toys and convert into a second sleeping space when you're parked for the weekend. Grand Design built the 381MS around the idea that you shouldn't have to choose between roughing it and living well, so you get a spacious kitchen and upscale interior alongside the hauling capability. Owners consistently call it the highest quality coach on the market, and with sleeping for seven across the main cabin and garage, it handles a full crew without feeling cramped. This is a rig that earns its place at the trailhead and at the resort.

2024 Grand Design Momentum 381MS:
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 to make meal prep and cleanup both easy and enjoyable. A freestanding dinette adds a touch of residential style and gives you a comfortable spot for dinner, cards, or planning the next day’s adventure.
The master suite at the front is a true retreat. With a slide-out king bed, generous wardrobe storage, and plenty of room to move around, it feels like a dedicated bedroom rather than an afterthought. The full bath is spacious and well-appointed with a roomy shower and quality finishes that make everyday routines feel effortless.
Outside, thoughtful touches continue — a long power awning with integrated LED lighting expands your outdoor living space, and heavy-duty exterior storage keeps tools and gear organized and accessible.

It’s ideal for adventurers who demand comfort without compromise, versatility without clutter, and a trailer that’s as ready for weekend thrills as it is for extended journeys.
