With our ViewFinder we had problems with the a/c and stove. In each instance we called the component's maker and talked with their warranty people. They were able to tell us who and where their authorized services places were in our current area.
There were dealerships, repair shops and even a couple mobile RV services on the list. We just called down the list until we found ones that could get our stuff fixed the soonest.
We paid for the service call/appointment and were later reimbursed by the company since we had the repairs pre-authorized. The repair place was paid by the component maker (and to be honest I'm not sure how that end of it worked).
With the MH we take it to the manufacturer in Red Bay or to Freightliner if it's a chassis or engine issue.
I don't recall ever going back to the original dealership for repairs on either RV, now that you mention it.
