Oh wow, Paul, you did it right! I see you went for 6 regular and 6 seafood racks, as well as the jerky shelf holder! You should be able to smoke about 1,000 lbs of jerky in that rig!
Just kidding! You won't be able to do more than 500! LoL! Seriously, though, that's a LOT of Real-Q-Estate! You should be able to smoke for a little league team, or a small army.
I look forward to news of your massive successes in the #4!
