I have cooked enough briskets to equate to a house, usually 50 to 70 at a time. I wanted to build a UDS (Upright Drum Smoker) because firing up my Meat Mama 3000 and Brazos Stick Burners are so expensive if you are not smoking a big load. I also like sleep and this puppy with my Big Ass Firebasket Design smoked nearly 20 hours on 16 pounds at 230 degrees. Needed only one kick at 12 hours to settle the ashes. Not that I will ever use 20 hours worth of burn but dang if it won't hold at 150 for hours too.
Maybe its the twin one inch internal draft?
Also in the video.... My Rub Process. In 2006 or so I perfected the "Tri-Level Rub method." Now you can see an update... For those also wanting to see both the cooking quality of a UDS AND the whole Butcher Paper thing I have used for years, here it is.
