GVWR (the sticker maximum)11,445 lb
Tongue weight, loaded~1,402 lb (13%: low, watch for sway)
Cargo capacity2,112 lb
WHICH TOW VEHICLES IT FITS: 26 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 310BHI's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
