WHAT ONE COSTS
$58,900est. used (2021, 5 yr old)

WHAT IT WEIGHS BEHIND YOUR TRUCK
~14,079 lbestimated as towed, for 2 people

dry weight 12,729 lb + fresh water (66 gal, full) 550 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

Tongue weight, loaded~2,964 lb (21%)
Cargo capacity3,951 lb
WHICH TOW VEHICLES IT FITS: 19 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 3230CK's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
