I have to say, i'd hate to see you waste your time, I did.
I used 3 Stainless drums to build a double drum set up.
Its not worth the extra rack space as far as I'm concerned, you don't get the flavor or bark and its a bitch keeping the temp in range.
But sometimes you just gotta learn yourself, maybe you'll make it work!
Whatever you decide, let us know how it goes!
