Adventure starts the moment you load up the NEW 2026 Grand Design Momentum G-Class 325G, a toy hauler built for riders who want serious hauling power without sacrificing comfort at camp. Whether you’re heading to the dunes, desert trails, or your favorite off-road park, this Momentum is designed to keep up with your lifestyle and then help you unwind in style.

The 15' garage gives you plenty of room for ATVs, dirt bikes, or side-by-sides, secured with heavy-duty, chassis-anchored tie-downs. Once the toys are unloaded, this space easily transitions into additional living or sleeping space. The rear ramp door converts into a patio, expanding your campsite and creating the perfect spot to relax, take in the views, or keep the energy going with the exterior speakers.

Inside, the main living area opens up thanks to a slide that houses the roll-over sofa and large 15 cu. ft. refrigerator, creating extra room to move around while you cook or entertain. The fully equipped kitchen features a flip-up countertop extension for added prep space, making it easy to handle meals after a full day of riding. Thoughtful touches like the flip-up pet dish ensure every member of your crew feels at home.

The full bathroom includes a walk-in shower with skylight, ideal for rinsing off the dust and grime before settling in for the night. Up front, the private bedroom offers a quiet retreat with a comfortable queen bed and convenient USB charging, so you can rest up and recharge for the next day’s adventure.
