I'm assuming that they are always 12V but that is landline power inverted to 12V. Is that right?
I'm looking for a 12V source to install a radio.
Your interior lights are 12 vdc, power which is supplied either by the battery when not plugged into shore power or by the converter (not inverter) when the trailer
is plugged into shore power.
Just pull 12 vdc from any nearby 12 vdc source, a light switch or fan switch for example - just make sure it's before the switch connection, not after ... obviously. ;)
