Grand Design Momentum M-Class toy hauler 351MS highlights:

Bath and a Half 11' Separate Garage Dual Entry Doors Kitchen Island with Bar Stools Overhead Loft Bed Universal Docking Station

Traveling with friends and family can be comfortable when you have a full double entry bathroom and a half bath available when camping and enjoying the trails on your off-road toys! You will have an 11' garage space that can become a second living/dining area, and you can add the optional Liftsuite System for more sleeping space. An overhead bed comes standard, along with a super sofa in the main living area where guests can sleep. Everyone can watch the LED TV when waiting for dinner, and enjoy the fireplace on those chiller nights. The kitchen island offers a sink to wash dishes, extra counter space for serving meals and two stools to dine at. The cook will love all the upgraded appliances, and the space thanks to the slide. The front bedroom gives you a queen bed slide with a king bed option, lots of clothing space, and a slide top dresser for even more storage.


With any Momentum M-Class toy hauler by Grand Design, you will enjoy luxury at every turn! They have been constructed to a superior standard with a thermal roof design, triple insulated main floor and garage floor, and a Rail-Tite underbelly seal that will allow you to camp in all elements. Each model also features an 8' 5" wide body chassis with a wide rail design, no wheel wheels, and a dovetail entry for easier loading. The Stealth A/C system provides maximum cooling power, and the CRE3000 suspension system means you can enjoy a smooth tow each time. You will love the luxurious interior with a professional grade stainless steel cooktop, interior color changing LED accent lighting, a fiberglass shower with a glass door, and solid surface countertops.
