WHAT IT WEIGHS BEHIND YOUR TRUCK
~17,292 lbestimated as towed, for 2 people

dry weight 15,800 lb + fresh water (83 gal, full) 692 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 around19,215 lb (10% margin)
GVWR (the sticker maximum)19,000 lb
Tongue weight, loaded~3,340 lb (19%)
WHICH TOW VEHICLES IT FITS — 14 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 380FL's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
