I noticed some of the new MES 40 Elite smokers have the vent on the top of the smoker on the left hand side..I have a earlier version where the vent is on the left hand side of the smoker. Any ideas on which vent location is better? I am not above relocating the vent from the side to the top if it makes that much if a difference. I use a Mail box mod with 9x9 AMNPS pellet tray that works awesome.
