A little background
I've been in the Air Force for over 21 years now, and love to cook. Growing up on me grandfather's fish farm in Arkansas, I learned to love hunting, fishing, and cooking early in life: gosh what else does a fellow need!
I'm not a "pit-master" but I have successfully hosted my church's annual pig roast for the last 7 years. The most I've ever served was around 300+.
This year I made my own smoker out of a 1948, 9.5 ft x 30" diameter propane tank. I made/welded up a 30" firebox, custom frame and placed it on a 3500lb axle. Nothing too fancy but it was my first hack at such a project, and am pretty happy with how it smokes so far. I cook with hardwoods, but I'm thinking about putting in a secondary heat source in the cooking chamber such as propane/natural gas so I can use it in the colder weather out here in Colorado. It is really hard to get the tank up to heat on cold/windy and/or rainy days.
