Lights Out

It sounds like your salesman's switch is turned off, or the relay it controls failed (they do that a lot)
Assuming of course that your safari is a Monaco under the skin.

I have a "salesman's switch" on the panel right inside the door, the front of the passenger armrest. It control's a big relay in the front run bay (drivers side front basement compartment) and it turns off most of the 12 volts, lighting and all that, but does not shut off the fridge and heat and such.

Are you sure these are all 12 volt lights? I think my florescent lights are 120. Not positive and not home to check. Check breakers.

Yes, no power & lights out.

Encore,

Did you actually test the power feed to those lights?
There are lots of things that can be wrong, but one must start with basic diagnostics.
