Just learned of this website which "helps" locate Ford Commercial Vehicle Centers to include Class C. I tested it before posting for my area and it was "mostly" accurate.
Commercial Vehicle Center (https://fordcommercialvehiclecenter.com/findDealer/init#!)
Hope this is helpful.
I’ll agree with the “mostly.” The first one on the list in my area was dead wrong. Will not handle RVs at all. The second was the one that I have used. It’s a good resource for locating possible sources while on the road in unfamiliar territory. Thanks for posting! — Jon
