I walked outside the other day and heard music playing, found the stereo in my TSBH32 was on. As I approached, it turned off. Checked it and found the power was indeed off. Several days later I was moving the trailer and the stereo came on, then turned off. Yesterday I heard it come on again, by the time I reached the trailer, it went off again. Power is always off when I check it. Has anyone had this problem, or do I have a ghost living in my trailer?
