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 388FKH's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
