FINDING ONE

Findable: a few listed nationwide most weeks. Why: Thor Motor Coach is a volume manufacturer; an uncommon body style. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

King-bed-lounge plan and the only Sequence with a 16 ft awning rather than 12 ft.
