I found the one side of my smoker was bowed in. Had to get a small pry bar in the vent slots and pull it out a bit to make the racks fit better. Water tray was extremely tight and had to adjust that as well.So far the smoker has been good but today I noticed my racks barely fit on the slots . One rack actually fell when I put the pork shoulder on it. Seems like the racks need to be tighter? Anyone else see this?
