OK, being that I'm pit poor and can't buy a Cookshack, I decided to build my own smoker. I have this Stainless Steel Cooler. I am going to use the Smoke Daddy Pellet Hopper asssembly. Here's a quick question. Where should I put the smoke stack? The inside dimensions are 27" deep and 23" wide. More than enough space for racks.I was thinking of cutting a hole on the back of the fridge, about 4" dead in the middle, then use the louvre plate i still have as a baffling system. Thoughts?
