WHAT IT WEIGHS BEHIND YOUR TRUCK
~15,370 lbestimated as towed, for 2 people

dry weight 13,944 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 around17,080 lb (10% margin)
GVWR (the sticker maximum)17,999 lb
Tongue weight, loaded~2,530 lb (16%)
Cargo capacity4,055 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 390RL's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
