Forest River Rockwood Ultra Lite 2921RL
Still in production. A used 2023 would run roughly $39,900.
dry weight 8,143 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 2921RL's published weights held steady.
