WHAT ONE COSTS

WHAT IT WEIGHS BEHIND YOUR TRUCK
~5,824 lbestimated as towed, for 2 people

dry weight 5,024 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

GVWR (the sticker maximum)6,400 lb
Tongue weight, loaded~632 lb (11%)
WHICH TOW VEHICLES IT FITS: 67 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 221RBS's published weights held steady.
