2026 Grand Design Momentum G-Class 25G

2026 Grand Design Momentum G-Class Toy Hauler – Premium RV Travel Trailer (Floor Plan 25G)

Meet the 2026 Grand Design Momentum G-Class, a high-end recreational vehicle designed for adventure seekers who demand space, durability, and convenience in a towable RV. This new toy hauler combines rugged capability with modern comforts, featuring a rear ramp door for easy toy loading, a durable dual-axle chassis, and a thoughtfully appointed interior that sleeps up to six. With a 30 feet 11 inches length, 8 feet 5 inches wide exterior footprint, and a height of 12 feet 4 inches, it’s sized for confident highway travel and comfortable camp setups. Floor plan 25G delivers two full slides for open living, a generous kitchen, and a versatile rear cargo area that doubles as a living space when your toys aren’t loaded.

Why This Momentum G-Class Stands Out

Built for serious travelers, this Grand Design RV combines a robust exterior with a comfortable interior. The two-slide layout expands living space, making room for a full kitchen and a relaxing lounge area even with gear loaded in the rear cargo. With a generous payload capacity and a practical bumper-pull hitch, it’s a reliable travel trailer for family road trips, weekend escapes, and outdoor adventures. The Momentum G-Class is engineered to handle long trips while delivering the comfort, safety features, and entertainment options modern RV enthusiasts expect.
