I found some one that has two 500 gallon fuel tanks in his basement. Problems: 1. They are in his basement and with past remodeling will not get up the stairs in the size that they are in. 2. They used to hold fuel oil and I understand that can stink pretty bad for a long while if spilled How does someone as determined as me get those tanks out of there? Is it worth trying to get them out and use as a smoker?
