New 2026 Grand Design Momentum G-Class 325G Toy Hauler Fifth Wheel

The 2026 Grand Design Momentum G-Class 325G is a fifth wheel toy hauler built for maximum garage space, extended travel capability, and residential comfort. Measuring approximately 35.5 feet in length with a dry weight starting around 11,600–12,600 lbs, it offers a strong balance of cargo capacity and livable interior space.

The standout feature is the 15-foot rear garage, providing ample room for motorcycles, ATVs, or large gear. Once unloaded, the space converts into a flexible living and sleeping area with a Happi-Jac bed system and seating. The ramp door also transforms into a patio, expanding outdoor living space at camp.

Inside, dual slide-outs open up the main living area, creating a functional layout with Euro chairs, a rollover sofa, and an entertainment center. The kitchen is equipped with a residential 15 cu. ft. refrigerator, three-burner range with oven, microwave, and flip-up counter space for added prep area.

The front private bedroom features a queen bed with wardrobe storage, offering separation from the main living and garage areas. The full bathroom includes a large walk-in shower and convenient layout for extended stays.

Built for longer trips and off-grid use, the 325G includes oversized holding tanks, a 60-gallon fuel station, and solar prep. A tankless water heater, high-capacity furnace, and dual A/C system provide comfort in a variety of climates, while the heated and enclosed underbelly supports four-season camping.
