FINDING ONE

Scarce — months of watching; be ready to fly and drive it home. Why: only one model year; still in production. Estimated from build volume and production span — not a count of live listings.

THE READ

The short Super C - 35'7" and two slides, for people who want the chassis without 39 feet of coach.
