I bought an OKJ Highland from Walmart for 138.00. I think I got a good deal. I went to bbqsmokermods.com, I have ordered a gasket kit for the cook chamber and firebox, rtv for the firebox halves and firebox cooking chamber connection, I got the cooking chamber lid latches, a tuning plate, and an expanded metal insert for the firebox. SO I have a few questions. 1) Should I get the elbow to bring the exhaust to the cooking plate? I have been reading conflicting info on this when there is a tuning plate used. 2) Should I use a water pan in the cooking chamber? 3) I ordered a couple of thermometers with 2 1/2" stems to place down near the cooking grate. Was this a mistake and I should have went with 4"? 4) I also bought a Maverick 733 and am wondering about placing the cook chamber probe, where is the best location? Also do I need to worry about the probe wires getting hot? Can I just run the probes out the cook chamber door or should I plan on drilling holes? Thanks for the help.
