Query: Well made but....

I purchased this item in May, 2011 and it worked well throughout the summer. However, when the late summer and fall rains began, I noticed that it mildewed on the plastic liner inside. I cleaned it off with a mixture of clorox and water, but with the heavy dews I know it will continue to mildew because it is damp inside every morning I have checked it. Sooooo, if you life in a dry place, this cover should be great. I'd avoid it if you live in a damp climate.
