As posted previously, I recently purchased a GOSM 3405BGW from WalMart. It only has one damper on top and not a lower side one (as I have seen on others). I have smoked numerous things and have had no problems getting it to "cruise" around 225 degrees and overall I am very happy with it. The only "mod" I have done is replace the tiny wood box with a metal plate. The only concern I've had is the smoke output. I noticed that I needed to reach temperatures around 250 degrees to get the TBS started and then I would reduce the gas flow to lower the temperature back to 225. The smoke would eventually stop and I would repeat the process, very aggravating for me. Just recently I noticed that when I opened the door to mist/turn what ever I'm smoking, the TBS would began flowing almost immediately. I then realized that I need airflow from the bottom to obtain the TBS I have been working for with this smoker. Not wanting to start drilling/cutting holes in my GOSM unless I have to, I have been using a small wedge of wood to insert at the bottom of the closed door to pry it open just enough to get the air flow and not damage the door. I have not noticed any difference in maintaining a steady temperature in doing this, but, guess what, she smokes at 225 degrees (and lower) now! So, I wanted to get the opinion of my SMF family. Should I keep on wedging the door or should I order another damper plate and cut the holes to make a damper at the bottom side?
