I have read and learned so much from this site that I thank you, my family thanks you, and my neighbors thank you all! I bought the new 40" MES right before New Years eve and smoked 8 racks of ribs for my first smoke. Thanks to all the reading and advice from this site, I came out a hero. Having said that, with all the reading on this site, I swear I read a very informative thread started my some thermal engineer where the subject of temperatures in the smoker was addressed. My key takeaway from that thread was, to accurately gage the temperature in the smoker, it would be wise to put a cup or bowl of oil in the smoker, then insert the probe into the oil then use that reading, otherwise, expect wide swings in temperatures in different locations in the smoker. Please understand that is statement is being made/semi quoted by someone who has about two weeks of smoking experience and is making his first post If I find that thread again, I might post the link here.
