Congratulations Scott! You are going to love your new beast of a smoker. I'm not guaranteeing that you won't have any hiccups, but the learning curve is short and the results are awesome!
BTW, if your seasoning doesn't go as planned with the Auber don't get too worried. These things are tuned to be used with meat in the smoker. So, some have seen issues with the temps during seasoning. Not anything to be worried about.
I am looking forward to the day when I can spring for a #4.
BTW, good luck on your catering business!
