HI, I have been lurking here for a while, and have been smoking every now and then in my spare time. I have a Snap On kamodo smoker, which is a Brinkmann Trailmaster. I built one reverse offset with the firebox too high, and only 1/8th the size of the cooking chamber using half of a 176 gal propane tank. I am currently working on a new reverse offset with the other half of the tank.
