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?

Do you have an Automatic Transfer Switch that switches between Generator and Shore power? The big relays in the ATS will sometimes hum. That is fairly normal for them. I can hear mine if I have the door to the electrical bay open, but can't hear them in the MH even though the electrical bay is directly below the bedroom.
