I have been smoking for about 10 months. My first smoker is a smoke hollow 44". I like it but learning more every time I use it. I am thinking about building a reverse flow off set smoker that I can use Lp or charcoal. Is it possible? Thinking 2 different fire boxes. I want to be able to have that option. I am a heavy equipment mechanic In Indiana. Any idea would be appreciated , thanks Will
