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 336RL'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: Shasta is a volume manufacturer; 10-year production run; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Longest-running current-generation Phoenix. Buy 2021 or newer - the earlier GVWR left almost no payload.
