FINDING ONE

Patient search — weeks of watching, and probably some travel. Why: only 2 model years; 20 years out of production. Estimated from build volume and production span — not a count of live listings.

THE READ

First Sightseer to get the PowerLine energy management system standard; a 33-footer still on the 18,000-lb chassis.
