That may have been the problem. The heat escaping through the bunk ends and the cold temps outside seem like the culprit. That used to happen to me in my Coleman alot. Unzipping the ends should elminate most of the moisture. But have it known, when temps are that low and the heat within the unit is high, there will always be condensation. Venting is a must.
