FINDING ONE

Findable — a few listed nationwide most weeks. Why: 10-year production run; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ

The long-running flagship: 45 feet, tag axle, walk-in closet and a bath and a half. Nine straight model years and still the plan most Bus buyers pick.
