I swapped out my coal bowl for the grilling wok - works well. I replaced my water in the pan with sand, covered by tinfoil - works well I think. Problem : my temp. wanted to stay really high - 285 or so. I tried closing lower vents, removing coals, and opening door more often. Any suggestions on how to get this thing to level out? I like the smoker and am keeping it. I need some pointers.
