I have been watching all of these smokers being built and have aspired to build one for a long time. Unfortunately I have not been able to find a propane tank I have been looking for over a year now. Can a bulk tank work? 200 - 300 gallon tank?? I have access to a lot of them and know alot of people who have made them into large pig cookers but I would like to make a smoker and have not been able to find any examples or info. If you know anywhere I can find some info please share. Are these heavy duty enough to use for smokers. and are there other issues that may or may not work? Thanks for help and input looking for alot of it.
