WHAT IT WEIGHS BEHIND YOUR TRUCK

dry weight 14,340 lb + fresh water (76 gal, full) 634 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 around17,530 lb (10% margin)
GVWR (the sticker maximum)16,500 lb
Tongue weight, loaded~2,937 lb (19%)
Cargo capacity2,160 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 G390MLQ's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
