Phrasty your right about the doors. The right door opens or both. I don't mind that myself, and as far as the temp recovering quickly after the doors have been open... Hasn't been a problem.
As far as the size of my tank, I think its probably 100 gallons. It's an air compressor tank. Didn't have to worry about any explosion problems when I cut into it! (Not that I would worry too much about it once it was purged.)
As far as the smoker being hard to move around.... Well, it does weigh 620 lbs. however, I can load it and unload it on my utility trailer by myself. I originally had hard rubber tires on it. Would have been better off using logs and animal fat to move it! So I put the pneumatic tires on it.... made a world of difference
Wish I could be there for the inaugural smoke in Jamaica.... I know it will be world class Q!
