How private are those bathroom/bedroom slides?

It doesnt matter what is going on in there. The neighbors are going to hear ya anyway. One of our last trips this year our neighbors were wild fornicators. At first you could hear what sounded like the awning flapping in the wind, but it was dead calm. A couple minutes later we figured out that it was the trailer rocking when we could hear a very loud female voice moaning. I would rather someone hear me taking a dump.
