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 389BH's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Keystone (Mixed tier): The lighter half of Keystone's Montana family — a 101in wide body with frameless windows, six-point hydraulic auto-levelling, Curt slipper-roll suspension and a Helix pin box, plus a SolarFlex package standard. Good residential feel for the money; Keystone's volume-plant QC is the usual caveat.
