WHICH TOW VEHICLES IT FITS: 16 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 3965's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

Heartland (Mixed tier): Heartland (Thor): heavily equipped laminated toy hauler with MORryde CRE3000 suspension, 7,000 lb Dexter axles and a walk-on roof, but Heartland's fit-and-finish and warranty service are inconsistent enough to keep it out of the top tier.
