FINDING ONE

Findable — a few listed nationwide most weeks. Why: Coachmen is a volume manufacturer. Estimated from build volume and production span — not a count of live listings.

THE READ

The only slide-out Orion — a rear-sofa lounge that flips into a short queen, so the living space stays open by day.
