2026 Grand Design MOMENTUM G-CLASS Overview

2026 Grand Design Momentum G-Class 350G Toy Hauler Fifth Wheel highlights: • Front Queen Suite • Front Bathroom • Mid Living • Mid Kitchen • Dual Entry • Rear ½ Bath • 14’ 6” Garage Standing beside the 2026 Grand Design Momentum G-Class 350G here at Clear Creek RVs in Abilene, Texas, you can immediately feel the rugged power and premium quality built into every inch of this toy hauler. Whether you’re headed for the dunes, the mountains, or your dream adventure spot, the 350G is designed to haul your gear, fuel your adrenaline, and keep you comfortable no matter where the road takes you. Let’s start on the outside. This unit is built with Grand Design’s legendary construction: laminated aluminum-framed sidewalls, triple insulation layers, a fully enclosed and heated underbelly, and heavy-duty MORryde suspension for smoother towing. It’s ready for all-season travel and built to last. Out back, you’ve got a spacious 14'6" garage—plenty of room for your side-by-side, dirt bikes, kayaks, or whatever else you roll with. Heavy-duty tie-downs keep everything secure, and the Zero Gravity rear ramp door makes loading easy. Once you’re parked, convert the garage into a second living space or sleeping quarters with the Happi-Jac rollover sofas and top bunk. And yes, this bad boy has its own half-bathroom in the garage—because you don’t want dirt-track boots walking through your nice clean living area. Need to refuel between rides? The 30-gallon onboard fuel station means you're not stuck hauling gas cans around. Just pull up, fuel up, and get back to doing what you love. Now, let’s head inside. The living space is nothing short of luxurious—something you don’t always expect in a toy hauler. A reclining sofa stretches across the slide-out, perfectly positioned in front of the entertainment center with a large LED TV and fireplace. The kitchen is fully loaded, with a stainless steel 18 cu. ft. refrigerator, microwave, oven, three-burner range, and a solid-surface countertop with tons of prep space. There’s even a pantry for your snacks and a stainless farmhouse sink that makes cleanup easy. The front master suite features a queen bed slide with storage underneath, a wardrobe, and an additional dresser. The bathroom offers a walk-in shower with a skylight, a porcelain toilet, and linen storage. Whether you’re full-timing or weekending, you’ll feel like you brought your house with you. And like all Grand Design Momentum models, the 350G is prepped with all the smart features: solar-ready, generator prepped, and loaded with USB charging ports, motion-sensor lighting, and even a central vacuum system. Here at Clear Creek RVs, we work with over 40 nationwide lenders, which means financing options are available for just about any credit situation. Our experienced finance department is here to help you find the best plan for your needs, so you can focus on planning your next adventure instead of worrying about paperwork.
