I wish there was a way to automatically switch the heatpad power input from 110V (when the RV is connected shoreline power) to 12V (when it's not connected to shoreline power).
That way I would not have to worry about both 12V and 110V powering the heatpad and potentially damaging it...
Right now, it seems like a human would have to make sure the switches are never on at the same time (12V and 110V) when there is shoreline power available. Maybe I could have a switch that chooses the input and one that turns the power on (in series)...
