I'm new to the world of smoking meats and I have a very small trailer unit. I've used the smoker about four times now and I am really struggling to keep my temp consistent. my biggest issue seems to be when i am trying to add a log to the fire. I can have it running along smoothly at 275 but when I add a log to the fire it drops 25 degrees immediately when I open the door. Is that pretty typical with most smokers or is there a reason/smoker setup issue that its causing it to drop temp so quickly when i add a log?
