When i got my 5th wheel I had a mystery switch like that. Tried everything in the trailer...
Then one evening I was flipping the switch off and one and the wife comes in the trailer and asked me why the two real large lights on the outside of the trailer was going on and off...
Turns out it was the SCARE lights on both sides of the trailer near the rear was what was being controlled...

These light were great for backing into a camping spot... Being on the side of the trailer up high they did not fall under any DOT Lights requirements rulings...
Try flipping the switch on your mystery switch after dark and see what may light up outside the trailer...
