We have for sale a very large Cooker/Smoker on a 12 Ft. trailer. The cooking/ smoking area is 4 feet long and 3 feet wide with 2 sliding cooking racks on 3' X 4' grating. Notice the 3rd arm that comes with it to slide the grating back and forth..The smoke stack has a damper and a thermometer. The fire box is 34" long and 20" round and i doubles as a grill for grilling burgers and hotdogs. It is solid and well worth the money. A friend of mine here in Shelbyville just built a new Smoker and the cost of all parts and trailer was $3500.00 This wasn't even counting any labor. The overal length is 12'2" and overal width is 60".
