Hello, my name is Ryan. I smoke just about every weekend and there is just never enough smoked meat for left overs so i'm planning on building a bigger and better smoker. I just picked up a 275 gallon oil tank last week and I plan on making it into a smoker. I know the basic on how to clean it. I am not going to laying it down so it opens like a clam shell. Should I use a firebox? I'm going to make double doors on the front and a door on the side that opens with a pull out pig rack. What do y'all think about this. Any suggestions?
