WHAT ONE COSTS
$53,700est. used (2022, 4 yr old)

Sticker was $89,505 in 2022. Out of production since 2022, so the used market is the only way to buy one. Estimate assumes a 2022 unit.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~15,192 lbestimated as towed, for 2 people

dry weight 13,842 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.

You want a tow rating around16,880 lb (10% margin)
GVWR (the sticker maximum)16,500 lb
Tongue weight, loaded~3,090 lb (20%)
Cargo capacity2,658 lb
WHICH TOW VEHICLES IT FITS: 18 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 382FL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
