Sorry, I cannot help with a reliable mechanic in Oklahoma. But if your generator is running some circuits but not others, it most probably is a breaker on the generator or your load center. And you do not say what kind of MH you have but it has been my experience repair like an exhaust leak is better fixed at a vehicle repair facility than an RV repair. They are usually less expensive. Hope this helps.
