Just curious about something I noticed last week on our trip. We were plugged into shore power for the week, so we weren't dry camping.
If we had 2 of the interior lights on, there was no "whirring" noise (a fan I assume) coming from the location of the power centre. If we turned a 3rd light on or ran the water pump, the noise would begin (very low).
Is there a reason why the fan (again I'm assuming) would only come on when the load was increased? Wouldn't the converter be running when the 1st 2 lights were initially turned on?
