Sorry I haven't posted back on here in quite some time. I Received the convection plate shortly after completing the project. I have to say that it does help regulate the temperature across the cooking chamber fairly well. There is still a cold and hot end but the temperature difference is much less dramatic than it was before.
Over the last year I have fine tuned my cooking process and have the smoker nailed down pretty well. I picked up another identical smoker as well. Had only been cooked on twice in over 10 years. Haven't made as many mod's as my first one, but plan on getting it up to par soon. I'll post pics when i start the process.
