Starting building my second smoker. I recently found out that i didnt have enough space on my 80 gallon smoker so i decided to go bigger with more shelves and space. Came up with using a old 265 gallon fuel oil tank built on a trailer. Making it a reverse flow. With many discussions duck killer 1 and his help and knowledge i decided to start this week. donor tank with the doors cut out. outside frame of trailer getting squared and trued before welding. latteral bars installed and welded. Thats all for now will be working on adding axel and toungue tomarrow.
