Radio

I have a 19 ft KZ classic. Once while camping my installed stereo radio would come on by itself. It did it several times within a few hours,,then quit. Now when its parked at home,,I've went out to check on things and found the radio on again. My trailer is always plugged in when its at home. I suspect the battery charger because years ago, I had a pop up coleman that I kept plugged in at home. At the time, my touch lamps in the house kept coming on and off on their own all day and night. The trickle charger in my pop up was affecting the lights by back feeding electronic signals in the wires.

I'am not saying this is the problem but I am going to let the dealer deal with it. Just wondering if anyone else is having this same problem. And no,, its not a poltergeist!! The camper is a 2014 model.
