Maybe you had a problem before and now it works correctly?
Historically, in-dash radios have always been powered by the house batteries. They do get their memory power from the chassis battery though. Maybe an unintentional wiring problem there?
Have you got your wiring "schematics" for your coach from Thor yet? Probably gonna need those to do any real troubleshooting.
