After reading the last several pages of posts on modifications to the Dyna-Glo offset I decided to post a reply on what I have done and what I still plan to do. First off I have sealed off all leaks as others have done. Also the biggest mod I have made is to insulate the outside of the smoker which has really helped in keeping my temps in and also reduced the amount of fuel needed which I figure will pay for the insulation in a short period of time. I have also played around with the damper effect by putting one of the shelves at the lowest position and wrapping it with Aluminum foil from the FB end to within about 6 to 8 inches from the opposite end of the smoker box. When using my digital thermometers placed in 4 locations in the smoke box I found I was able to maintain temperatures through out the entire smoking area, top to bottom at pretty much even. I plan on having a local fab shop make me a damper to slide in so that I can utilize all of my shelves when cooking. I will post photos of that mod once it is finished. Today I am adding the photos of my insulation job and hope that all enjoys what they see. Enjoying all of the comments on here and have learned so much. Thanks to everyone.
