FINDING ONE

Patient search — weeks of watching, and probably some travel. Why: only 2 model years; 15 years out of production. Estimated from build volume and production span — not a count of live listings.

THE READ

Longest Sightseer built and the only one with real bunks plus a king - a family coach at 38 feet, with front and rear awnings.
