Went inside the goose neck today first time in weeks and the inside top of goose neck was covered in ice and water.Temps have been in the lows teens several nights with highs in the 30's. I have noticed before where the walls have sweat during winter months but nothing like this. I am thinking maybe being so cold inside and then the heat from the sun on the outside during the day causes it.Any one esle have this problem, and if so is there a fix the trailer has no roof vents if that would help.

The sweating is caused by having warm, moist air inside the trailer, and cold air on the outside. Anything you do to equalize the inside and outside temperatures will help. Also look for sources of moisture inside the trailer.
