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.

OUR TAKE

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