HELP!!! I own a Longhorn Deluxe smoker. I have had it for 5 years and just this week the smoke box decided to rust through. I can use it a little longer but it won't last the summer. Char Broil no longer carries replacements and they claim there are no drawings for me to build from. Does anyone have the drawings or access to a replacement. I live in Northern Virginia where smoking meats is almost not heard of.
