Virgil,
By this time I hope you have received your new WSM and it included the cover. One important thing I learned on this forum is that the cover is not waterproof. If you leave your covered WSM out in the rain it will most certainly gather water in the bottom charcoal bowl. I, like many here on the board, keep my WSM in the garage or under some type of cover. Just something to think about.
Enjoy!
