After reading a lot of the threads here, I have what looks to be a pretty cheapo smoker. I can't add chips without opening the door, I have no venting except for a small hole in the top right corner, and when seasoning the unit, there was plenty of white smoke coming out through the door. Am I going to be able to use this unit correctly? Any advice is greatly welcomed. Please help me be successful on my first smoke. I have added a pic to show the smoker that I have. Thanks in advance guys/gals.
