New 2026 Grand Design Momentum G-Class 415G
The New 2026 Grand Design Momentum G-Class 415G delivers serious toy hauler capability combined with luxury fifth wheel comfort, making it an incredible choice for riders, racers, and adventure seekers who want to bring their toys without giving up residential living features. Grand Design’s Momentum lineup is known for premium construction, innovative floorplans, and high-end finishes designed for travelers who expect more from their RV.
The standout feature of the Momentum 415G is the massive rear garage that provides approximately 15 feet of cargo space, allowing you to bring motorcycles, ATVs, side-by-sides, bikes, or outdoor gear along for every adventure. Once you arrive at camp, the garage quickly transforms into a comfortable living and sleeping area with the Happi-Jac bed lift system, dual rollover sofas, and an additional loft bed above. This versatile setup allows the toy hauler to comfortably accommodate multiple guests or family members.
The garage also includes its own half bath, providing convenient access from both inside and outside the RV. This feature is especially useful after a long day of riding or outdoor activities when you want quick access without walking through the main living space.
Moving into the main living area, the Momentum 415G offers a spacious and inviting environment thanks to opposing slide-outs. Theater seating and a large sofa are positioned across from the entertainment center and fireplace, creating the perfect place to relax after a full day of adventure. Large windows allow natural light to fill the room while providing great campsite views.
The kitchen is designed for serious cooking while traveling, featuring solid surface countertops, a residential refrigerator, a three-burner cooktop, oven, microwave, and plenty of cabinet and pantry storage. A large island provides additional counter space and makes meal preparation easy whether you are cooking for two or hosting friends at the campsite.
Toward the front of the fifth wheel, the private master suite offers a comfortable retreat with a queen bed, wardrobe storage, and dresser space. The front bathroom includes a spacious shower, vanity, and additional storage so your daily routine remains convenient while traveling.
Outside, the Momentum continues to impress with large exterior storage compartments and power awnings that create an inviting outdoor living space perfect for relaxing evenings at the campground. Built with Grand Design’s reputation for quality and durability, the Momentum G-Class is ready for serious adventures.
