Our main interior ceiling lights have stopped working. I've checked all the fuses and they are good. The switch on the control panel itself still lights up but if you toggle the switch the lights do not come on. Any ideas on how to fix this?

Is, perchance, the dimmer all the way down?

How did you check the fuses? You might have to pull the switch panel out of the wall and verify that you have power leaving the switch. Check for any ground wires that might have come apart... the factory tends to squeeze too many of them under one connector. If you have 12V power leaving the switch next I would pull the light out of the ceiling that's closest to the panel and check to see if you have both + & - to the light.
Let us know what you find out.
 
Check the connections on the switch? Not sure what style they are but if they are blade style it's very possible one vibrated loose.

For the fuses first I checked the red lights next to them. None of them were lit. Then I pulled each fuse and check them with a continuity tester. They were all good. A few hours later though, just as mysteriously as the lights stopped working, they started working again. There must be a loose wire somewhere.

Schwenksville? We live outside of Pottstown in Chester County. Not far away at all.

Thanks everyone for your replies and have a Happy New Year.

Pop the panel out and check wiring and operation. With a lighted switch, you should have a 12V and ground that likely pass to most switches on the panel. Check for 12V between them.

Then move the red meter probe to the other wire that goes to the lights. Should be 12V when on and 0V when off. If not, the switch isn’t working. Jump across the 12V in and the output wire and the lights should come on.

Yes, we're practically neighbors!
That's the correct way to check the fuses... some just check for 12V on each side of the fuses without removing them.
Did the lights come on without flipping the switch or did they come on as soon as you flipped the switch? Either way I would pop off the trim around the panel with the switches, remove the screws and pull the panel to start checking things out.
 
I had the same issue. All of the ceiling lights in front half of my 5th wheel quit working. Turned out to be a broken wire connector in the ceiling. Good luck.

I had similar issue. We loosened main cabin "control switchboard" finding a loose wire detached from 'wire nut' leading from "ceiling lights" rocker-style switch. Reattach success! Disappointing screw nuts used in RV. Sheesh!

We had the same issue. I had to reconnect two of the lights and their switches.
