Forest River Rockwood Roo 21SS
Sticker was $46,255 in 2023. Out of production since 2023, so the used market is the only way to buy one. Estimate assumes a 2023 unit.
dry weight 5,047 lb + fresh water (54 gal, full) 450 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 21SS's published weights changed mid-run.
