We’ve never had those weird noises coming from our regulator.We got two more nights in our Camp-X a week ago. When we rolled up the camp we noticed there was a bunch of it antifreeze underneath the sink. I haven't had time to figure that out yet. One thing that we found weird is the propane regulator makes a really loud rhythmic noise. It almost sounded like water dripping in a sink. Has anyone else experienced a loud regulator?
