FINDING ONE

Findable — a few listed nationwide most weeks. Why: Thor Motor Coach is a volume manufacturer; still in production. Estimated from build volume and production span — not a count of live listings.

Rear-bath couples plan with theater seating, ten seatbelts and 119 cu ft of basement. Thor rates it for six, so a third convertible surface is present that the sources here do not name. MSRP shown is a dealer list price.
