I live in New York in the snow belt area. Try as I may when I clean off my truck I can't get all the snow off. When driving, what seems to happen is most of it blows away, but that I am finding that enough seems to congregate in the middle of the back bed. right at the back window. (In rear line of vision) Its like a little drift located right at the back window and it makes it very difficult to see anything in my rear view mirror. Is anyone else having this problem? If so, any suggestions??
