I stumbled across this forum searching for tips and such on building a smoker. I've got several years experience using a pits and spits offset smoker that belongs to a friend when I need something large and my modified chargriller for backyard stuff with great success. I am going to build a smoker for a friend who wants something larger using a 175-200 gallon fuel oil tank. I live in southwest Idaho and besides cooking I enjoy brewing beer (and drinking it) snowmobiling and working in my shop restoring antique Heaters/stoves. By profession I am blind guy with 20 years in window coverings and shade products, specializing in motorization.
