So my wife just bought me a smoker at the worst possible time, a week before thanksgiving. I usually like to mess around a few times on the smoker before doing a big production like thanksgiving, but she bought it so im not complaining. Its a limited edition Brinkmann Trailblazer Horizontal smoker. My question is: ith my 21lb turkey in a tin pan, i have 1 inch of clearance between the top of the bird and the metal barrel. Is this too close? if so, is there an issue with using the lower rack (i guess its there for tall items or drip trays) I know the most popular thing to do is replace the lower rack with steel tuning plates, but i dont have time for that. If youre not familiar with the smoker heres a pic i stole off a guys website. you can see 1 rack is at the 50% mark, and theres a lower one around the 30% Ideas?
