For a 27-foot travel trailer, the 21G punches well above its class. Owners consistently describe it as feeling more like a high-end fifth wheel than a towable. The 14-foot garage is the centerpiece, anchored by a laminated aluminum ramp door (R-12) that flips down into a patio, and the layout keeps the living area and full bath well separated from the hauler space. A 30-gallon onboard fuel station with both interior and exterior gauges is a genuinely useful touch for riders who hate making extra gas runs. The Rockford Fosgate speaker package with powered sub and under-unit accent lighting give the exterior setup real weekend-party energy, and solar prep with 10-gauge wiring and universal MC4 connectors makes adding panels straightforward.

The 2025 Grand Design Momentum G-Class 21G is a compact, lightweight toy hauler travel trailer designed for riders, weekend adventurers, and couples who want garage capability without the size and weight of a full fifth wheel. At approximately 26’11” in length, this model delivers a smart combination of cargo space, comfort, and easy towing for half-ton trucks and properly equipped SUVs.
Built on a wide-body bumper-pull chassis, the 21G features a functional rear ramp garage that doubles as a multipurpose space for hauling ATVs, dirt bikes, kayaks, or outdoor gear. When unloaded, the garage transforms into additional living and sleeping space using the convertible Happi-Jac sofa/bed system, making it a flexible setup for travel and recreation.
Inside, the main living area is designed for efficient comfort, with a single slide-out that expands interior space, typically housing a sofa or convertible seating and dining arrangement. The layout is open and practical, giving you room to relax after a day outdoors without feeling cramped in a compact toy hauler footprint.
The kitchen is built for functionality on the road, featuring a 3-burner cooktop, microwave, mid-size 12V refrigerator, deep sink, and overhead storage cabinetry. It’s designed to handle weekend cooking or longer trips with ease, while keeping weight and complexity down.
At the front, the private bedroom area includes a walk-around queen bed with storage and wardrobe space, while the centrally located bathroom provides a walk-in shower, toilet, and vanity, making it fully self-contained for extended travel.
The 21G is also built with Grand Design’s focus on durability and convenience, offering features such as:
