Terry,
I have a '62 Overlander (an International) as well, but no door above the bumper. I
too have no control panel, and also have no transformer or anything of the sort. What
I do have is twin circuits (one AC and one DC). The outboard side/front side of the
trailers lights are DC, the inboard/rear side of all these TWIN FIXTURES are AC.
My water (or is it air?)pump is under the sink, just toward the rear of the rig from
the furnace (against the wall.)
The more I learn about AS the more corn fused I get.
Oh well,
Ralph KE4UAK
