The other power draw, as I understand it, is the entertainment system. Ours has the front panel somewhat lighted up even when turned off. I think it's for the alarm that is build into the system. On our FW, we were told that both the entertainment system and the CO2 detector were fused inside the trailer. And the dealer suggested that we simply pull the fuses if we wanted to turn them off. Haven't done so yet, but may in the future, for now we plug into the house 30 amp plug-in we had installed when we build the house and keep the FW "hot" when we aren't using it.
