I have never smoked anything and I have moved into a house with a giant smoker in the garage. It is electric, seems to be 20-30 years old, and says "Harris" across the front. It has the capacity of a large refrigerator and a large smokestack out the roof. I am not sure if it works yet, but am thawing out a pork loin for the first attempt. What I really want to know is, for what purpose is the smoker so large? I can only eat so much meat at a time.
