So I could possibly be purchasing this smoker. I just started talking to the guy about it and I don't know all the specs. But, here is a pic that the guy sent me. He is sending me more tomorrow as well as the dimensions of the cooking surface and firebox. He said he used to use it at his restaurant to smoke ribs and it has two racks to cook on. The diamond plate box is for a motor to run a rotissiere. Any thoughts on this would be greatly appreciated! He is asking 600.00 but the price is very negotiable.
