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.

OUR TAKE

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