Hello, my name is John. I don't have a smoker right now but with your help I will have one really soon. I have never smoked and I live in a apartment, but I'm lucky I got a back deck. I plan on driving the neighbors crazy with the smell A friend recently brought me some smoked venison and I thought I had died and went to heaven. I asked where did he get it and he told me a neighbor did it. I contacted him and he sent me here. I'm thinking about getting a gas smoker because I'm not good with keeping temps with charcoal. maybe in the future I will get a charcoal smoker. So any suggestions on a gas smoker and how many smokes can I get out of a 20# tank will be greatly appreciated.
