Rant - getting someone to work on a Class C motorhome

I live in Memphis, TN, where there are a plethora of Ford dealerships. When I had my Ford chassis Class C, there was only one Ford dealership in Memphis with a service bay large enough to take the MH. It was the Ford dealership that worked on ambulances, fire trucks, and such.

Not every Chevy dealership has the facilities to work on something as large as a MH. However, calling one dealership should get an answer when you ask which dealership in the area can work on it?
