USED 2020 Grand Design Momentum M-Class 351M Toy Hauler Fifth Wheel – Built for Extreme Play and Serious Comfort

When your weekends revolve around horsepower, trailheads, and wide-open spaces, the 2020 Grand Design Momentum M-Class 351M is engineered to keep up. This rugged yet refined toy hauler fifth wheel blends high-capacity cargo space with residential-style comfort, giving you the freedom to chase adventure without leaving luxury behind.

The 11' garage is ready for ATVs, dirt bikes, or side-by-sides and is equipped with heavy-duty, flush-mount tie-downs to keep everything secure on the road. A half bathroom in the garage adds convenience during long days of riding, while large windows throughout the coach flood the interior with natural light. Dual enclosed fuel stations ensure your toys stay fueled and ready, so the fun never has to stop early.

Inside the main living area, this Momentum delivers a space that feels like a mountain lodge on wheels. The four-seat sofa offers a comfortable place to relax after a long day outdoors, while the fireplace and 49" LED TV create the perfect evening atmosphere. The kitchen island with bar stools becomes a natural gathering place for meals, planning the next ride, or sharing stories from the day. Overhead, the loft provides additional sleeping or storage space, making it ideal for families or riding groups.

Dual entry doors add flexibility and convenience, allowing easy access to both the living area and garage. Whether you’re hauling gear, entertaining friends, or winding down for the night, this layout is designed to flow effortlessly from play to relaxation.

Quick and Easy
We called and talked to Mackay Hirst about a certain toy hauler we were interested in. Mackay was so nice and knowledgeable on them and he wasn't pushy to get the sale like so many sales men are. I would recommend Mackay to anyone interested looking in buying a trailer.

Brian was so helpful in learning
