For those of you with the MES 40, what temp do you set it to smoke your Butts? Also, does water in the water pan affect the length of the smoke? How about if you are smoking 2, 3 or 4 Butts at a time? Should the temperature be set higher? I would like to be able to put my Butts on about 6 AM and have them ready in 11 to 12 Hours if possible.
