It sounds to me your auxiliary/120v compressors are weak or having some issues maintaining proper air pressure. How old are your auxiliary compressors?
Maybe it's time to get that replaced.
When the coach is running, your main compressor (powered by the engine) kicks in, and it was able to maintain enough air pressure, albeit minor leaks somewhere, so you don't observe an issue.
