I did a check of the 110 AC drawings for your RV and it looks like there are two different feeds for the outside entertainmnet center (TV there, I assume?) and the bedrooms which work through the inverter.

Or these snips may help follow the path if you click them to get larger better view?
Two different paths? Two different breakers as I marked and the outside not through the inverter?
See if that matches what you have as a clue.
