@retired157 I have a cook shack which is basically the same thing as what you have. Couple of things from what you are describing that you want to do. From the factory there is no vent adjustments, just a pinky sized vent hole on the top and same one on the bottom to drain grease. Now I see you added a vent to the door which will let some air in but it will probably get bottleneck with the small vent on the top. So you may have problems with the smoke schedule you described. Also with this smoker you will have trouble getting wood chunks to smoke (if at all) at low temps. Especially with the low temps in your schedule. With this smoker you really need a smoke generator to do what you described. You mY be able to get away using a smoke tube and a fan since you added the vent on the door. Get on youtube and watch 2 guys and a cooler videos. He has the smokin it brand of your smoker and has a smoke generator to do his sausages.
