just bought a MES40 going to get it seasoned and start going on it. Ive seen most people on here have bought the a-maze-n pellet rack for the smoker seems like a good idea to me. But also seen a lot of people making a cold smoker out of a mail box. is that used just for fish and cheese and that sort of stuff or is the cold smoker used for everything? I guess it would get hot enough if you have the main smoker on for heat only. Im guessing making one with the a-maze-n is better than the cold smoker that Masterbuilt sells right? Thanks for any tips. Been reading a lot of info on here so far.
