dry weight 12,277 lb + fresh water (48 gal, full) 400 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

Tongue weight, loaded~2,469 lb (18%)

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 391QSMB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
