I would be looking at the switch in the bunk area. Very common for the manufacturer to "daisy chain" the power and ground to several lights since the amp draw is low. Start at the light switch CLOSEST to the fuse panel. Using a test light or Ohm meter set to VDC, test for 12V coming into the switch. Odds are there will be at least 2 of not 3 or 4 grounds joined together with a big Bell connector.

The Positive lead will be the white WITH A COLORED TRACER on it, ground is solid white. Start at one end or the other and start testing. It seems like every time I do I seem to start at the wrong end.
