I have a 30" Mastercraft, two door, propane smoker, and I am having trouble maintaining tbs below 250 degrees. I have been using chunks that I have been trying to knock down to smaller pieces, but that isn't working. I have made all the recommended mods to the unit including using an 8" skillet to hold the wood chunks. I use a Maverick ET-733, so I know the temp is accurate. Will using chips or pellets instead of chunks fix this problem? I appreciate any advice. Thanks!
