Very large built like a tank smoker for sale. This isn't a cheap barrel made into a smoker like most. This was custom-made with rolled steel. You can fit 48 babyback ribs on it. Has 4 shelves that pull out for easy access to your product. I insulated the fire box for better efficiency. Top racks are 30x31 bottom racks 31x36. The main chamber is 72x38, and the fire box is 24x26. I've used it many times but just have too many smokers. It already has legs on to be easily mounted on the trailer. This is a heavy, well-built unit that will last a lifetime. I have a perfect draft fan that i will let go with the smoker. Can use wood or charcoal or both. IF YOU'RE READING THIS ADD IT'S STILL AVAILABLE. WILL NOT RESPOND IF YOU ASK IF IT'S STILL AVAILABLE.
