Hello this is my first post.i have a question and maybe some ideas from you.me and my family purchased a new 2013 heartland wilderness and went camping in it for the first time this weekend. The weather was rainy and cold, we had the heat on and noticed a large amount of moister build up on the inside of the glass. It was so much that the window tracks inside the rv were overflowing with water. We had to place paper towel in the tracks to soak up the water and keep changing them out. This is not our first camper we have had a little condensation build up on the glass of our old one but never this much. Any reason for this or suggestions thanks
