YEAR BY YEAR: WHAT CHANGED

2018First appears in dealer catalogues
2020Not carried into the final model year

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.

OUR TAKE

Late-run plan that appears in dealer catalogues for 2018-2019 but never in a Thor spec sheet I could recover - length, tanks and sleeps are carried from the sister plans on the same Sprinter shell. Verify against the door sticker.
