I first would look into removing the "escape" window in the living room. If you have power available, I would leave the power on. On my coach, the inverter is wired directly to the battery bank and does not go off when the master battery switch is turned to off. If power is not available, I would consider removing the negative cable from the battery bank which would also shut down the inverter.
