I’m going to guess it turns your tank heaters on/off.

Hmmm. Didn't know I had those. How do you know for sure if you have them? Dont see anything in the fuse box that leads me to believe i have them

It would be on a 110 circuit, so look at breakers vice fuses.

I dont want to lead you astray here, so i am going to tap out and ask @Rich W. to have a look. He’s pretty good at solving these mysteries.

Does it turn your water pump on/off?

If it's OFF do the awnings work? Is it a master on/off or awnings like I have in mine?

All my guesses have been used up. I’d pull the switch out, confirm power and determine whether 12v or 120v, then with it on start pulling fuses or turning off breakers and see what kills it. Or if all else fails, refer to the manual, but thats a last resort for me. Maybe its the “salesman switch”?

Do any exterior lights come on such as a door light or patio side light?

If you have a Winegard + it could be power for the optional gateway. I have a random switch like that on my 2022 F. R. Wildcat 5th wheel.
