Tongue weight, loaded~2,363 lb (19%)

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.
