WHAT IT WEIGHS BEHIND YOUR TRUCK
~15,019 lbestimated as towed, for 2 people

dry weight 13,593 lb + fresh water (75 gal, full) 626 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 around16,690 lb (10% margin)
GVWR (the sticker maximum)16,593 lb
Tongue weight, loaded~3,040 lb (20%)
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 389FL's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
