FINDING ONE

Findable — a few listed nationwide most weeks. Why: Thor Motor Coach is a volume manufacturer; only 2 model years. Estimated from build volume and production span — not a count of live listings.

THE READ

Tag-axle 43-footer with a pair of 12 ft awnings instead of one long one. Thor published 44,600 lb GVWR early in the 2017 run and 45,660 lb later - check the door sticker.
