I just picket up a Brinkmann vertical spli door from cabela's for 42.99 on clearance. Looks like a decoent littel charcole smoker, with vents on top and bottom, easy access to food, water, or fuel. However it has the same waste of a fire bowl as in all their other smokers. No fire grate, and I'm thinking I will need to find a way to insulate the doors some how to prevent to much heat excape. If anyone has one I would love to hear of what they might to have had to do to turn it into a decient littel smoke box.... thanks!!
