WHICH TOW VEHICLES IT FITS: 31 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 28DB's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.
