Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
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.

Available now at Campers Inn RV, this versatile travel trailer delivers the perfect combination of hauling capability, residential features, and durable construction.
Built by Grand Design, the Momentum G-Class lineup is engineered for performance and reliability, and the 21G stands out as one of the most versatile compact toy haulers in its class. Measuring approximately 26 feet 11 inches long with a dry weight around 7,280 pounds, it remains manageable to tow while still offering impressive cargo capacity and living space.

Inside, the 21G is designed for both functionality and comfort.

Up front, the private master suite with a walk-around queen bed slide provides a comfortable retreat after a long day outdoors.
The kitchen and living space are equally impressive, featuring residential cabinetry, stainless steel appliances, and comfortable Euro-style seating—creating a modern, inviting atmosphere. A dual-entry bathroom with a walk-in shower adds convenience and privacy, especially when traveling with others.
Built for serious adventure, the 21G includes a 30-gallon onboard fuel station, rugged tie-down system, and reinforced chassis—making it easy to fuel your toys and keep everything secure.
