FINDING ONE

Patient search: weeks of watching, and probably some travel. Why: 9-year production run; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Bath-and-a-half couples coach and the volume RED - 119 cu ft of basement plus a half bath up front so guests never walk through the bedroom.
