Took the camper out on our first trip this past weekend which was only 1 night. We had the AC going pretty much the entire time without an issue. The problem came when taking it down. Were in a hurry because it was starting to rain so it was very humid and moist outside. We turned off the AC and not long after water started dripping off of it into the camper. We wiped it off and closed up the camper. When I got it home I opened it to dry it out and noticed there were are couple damp spots where water had soaked through the sheets and into our mattress on the bed that was under the AC when the camper was down. Is this normal due to the conditions or is something wrong with our AC?
