WHICH TOW VEHICLES IT FITS — 20 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 321RSTS's published weights changed mid-run. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

Common — usually several for sale within a day’s drive. Why: Jayco is a volume manufacturer; 12-year production run; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ
