My new build is a 6' Rottisserie with a top mount warming box, and a rear mount firebox. It has 4 air intake dampers on the fireboxand 4 dampers between the firebox and cooking chamber. The rottisserie will turn at 1 rpm. Pull one lever and the firebox will dump ashes out the bottom. It will eventually be on a trailer with a custom built 2' x 4' charcoal grill, 3 gas burners for deep frying, SS refrigerator, and sink with hot and cold water. The trailer will have a roof with sides that will fold out to make a 4' overhang roof down both sides of the trailer. It is definately a project in the works, but the smoker is now ready for high temp paint. I will post updates as the build continues along with more pictures.
