OK new question. I have a try vet AC/DC cover for my MH, I under stand this a breathable cover. Here is my problem, I am getting mildew on the sides of the MH. I had this problem last year, but didn't find it until I took the cover off in the spring. But this year we have had 3 1/2'' of rain in DEC and the humility is up in the 80% range. I have found mildew again and have taking the cover off. So does anyone have a suggestion as why mildew is forming on the side of the MH.
