Hey, well I decided to build a smoker. Picked up a 500 gallon tank and a 100 gallon tank from the local co-op, which gave them to me for free. The 100 gallon will be used on top of the fire box as a smaller smoker/food warmer. Heres what I have so far! The door alone weighs about 200 pounds, so tyring to figure out what kind of counter weights are needed. Next is to get it mounted on the trailer and mock up the fire box.
