Just ordered the #2 and trying to absorb all the wisdom in this forum. Query; How much time should you add if you open door part way through proscribed cooking time and add new (and cold) foods to smoker? If you mix meats (poultry plus ribs or butts) or add vegetables (potatoes, corn) you're going to have different smoke/cooking times for each which would necessitate opening the doors to make additions. What is the recovery time to get back up to proper internal cooking temperature?
