Ok, I'm a little confused. I bought my mes 30 used and assumed i have aa water tray and chip box but no drip pan. See photo below. If thats correct, where would a drip tray go? 2nd question. Everyone says that you have to replace chips at least ever hour. I have lots of smoke when using chips soaked for 30 min. This is at 6 Hours and i havent reloaded chips yet.
