Do you know if you or a previous owner installed an "Amp-L-Start" between the chassis battery and the house battery? It's a long shot, but if one has been installed it will faintly beep if there is any issues with that connection.
This probably would not be installed by the factory on your year RV. So, it's not likely to be there unless someone installed it.
I have installed one, and it too is near the steps because that's a convenient location for that connection. If my Chassis battery is too low, or a wire is disconnected it beeps very slowly with quiet beeps.
Again, a very long shot. Just mentioning it in case and I know many people install these.
