2026 350G Features and Options

New 2026 Grand Design Momentum G-Class 350G

 

The New 2026 Grand Design Momentum G-Class 350G is built for adventure lovers who want the versatility of a toy hauler combined with the comfort of a luxury fifth wheel. Grand Design’s Momentum G-Class lineup is known for durable construction, smart garage layouts, and residential-style living spaces that make it easy to enjoy both the journey and the destination.

 

The 350G floorplan features a spacious 14-foot rear garage, providing plenty of room for motorcycles, ATVs, side-by-sides, bikes, or other outdoor gear. Once you arrive at your campsite, the garage easily converts into a flexible living and sleeping space with rollover sofas, a HappiJac bed system, and a loft above for additional sleeping capacity.

 

The rear ramp door allows for easy loading and unloading while also doubling as a patio space where you can relax and enjoy the outdoors after a day of riding or exploring.

 

The main living area offers a comfortable and open layout with theater seating facing the entertainment center. Large windows bring in natural light and provide great views of the campground, creating a relaxing environment to unwind after a day of adventure.

 

The kitchen is designed for convenient meal preparation while traveling. It includes a refrigerator, cooktop, oven, microwave, and generous cabinetry for food and cooking supplies. The layout keeps everything easily accessible whether you’re preparing breakfast before heading out or dinner back at the campsite.

 

Toward the front of the fifth wheel, the private master bedroom offers a comfortable king bed along with wardrobe storage and dresser space. This dedicated sleeping area provides a relaxing retreat at the end of the day.

 

The bathroom includes a spacious shower, vanity sink, and additional storage, delivering the convenience and comfort expected from a residential-style RV.

 

Outside, the Momentum G-Class continues to impress with exterior storage compartments for riding gear and travel essentials. The power awning creates a shaded outdoor living space where you can relax, cook outside, or enjoy evenings at the campground.

 

With its 14-foot garage, versatile living space, and Grand Design’s reputation for quality construction, the Momentum G-Class 350G is an excellent toy hauler for RV owners looking to combine adventure, comfort, and flexibility.

What Our Customers Are Saying

I will not shop anywhere else for our next camper!

We purchased a camper from a private party and were looking to get setup for the 4th of July. The service department was able to take time and go over the ins and out of my new to me camper and also install a solar charging system. I can’t Express how grateful I am and when it comes time… I will not shop anywhere else for our next camper!!! - Thomas
