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.
