WHAT ONE COSTS
$34,100est. used (2020, 6 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~10,946 lbestimated as towed, for 2 people

dry weight 9,729 lb + fresh water (50 gal, full) 417 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around12,165 lb (10% margin)
GVWR (the sticker maximum)12,729 lb
Tongue weight, loaded~1,828 lb (17%)
WHICH TOW VEHICLES IT FITS: 23 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 3220RL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
