Humming inside the TT
Not that it bothers me or keeps me awake, but what is that humming sound inside the RV when the shore electricity is plugged in?

Probably the cooling fan in the converter that charges the battery and provides 12V. Many are controlled by a thermostat thus the fan doesn't run when the batteries are charged and there is little 12V use.
Thanks, that makes sense. I appreciate your answer.
