12v or 110v house type switch?
It's a 12v switch. It's location is what's strange as it is near the floor right inside the door on the other side of the fire extinguisher. She took a picture and sent to me but I'm not sure how to post pictures on here. Regardless, hopefully they will figure it out today. She is one of those people that it will drive herself nuts (& me lol) until she knows what it's purpose is lol. I posted on here because I couldn't think of anything but maybe an under stair light and she immediately responded with "nope, I don't have one of those" so I know she had already thought of that and had been searching for another answer. I'll let everyone know what it is when we know. I appreciate all the guesses so far as it gave me some tips to help her figure it out when she gets battery power. They don't have a plug nearby to keep it plugged in but are getting an RV plug installed soon. Thanks again.
