I'm going to build a smaller smoker and have been tossing around the idea of a box rather than a cylinder. I can't find any disadvantages to it, other than the cosmetics. Lex, (my fabricator) and I, both seem to think that the box shape would simplify the building process and it will certainly make the math easier. We were thinking of trying to market a few of them, but are concerned the shape may turn people off. What is the opinions on the cosmetic factor? Would a box shaped, Reverse Flow smoker be marketable or should we go with a more traditional cylinder? Keep in mind that they will both be fully insulated and the CC dimensions will be 20" wide by 30" long. Let the debate begin!!!
