Nearly impossible to get Class C Chassis serviced?

The only thing I could give you in CO is the name of my Son-in-law but not sure he'd work on it either (It is not his primary job)
Here in Michigan there is an RV dealer / service that can do it. but alas that's a thousand or so miles away. And I know a shop in Georgia. but I'd find a mobile RV service tech. he or she won't likely work on "Chassis" systems other than jacks. but they will likely know who will..
