Hi Tim:
Welcome to the club. As a Model #2 user, I am envious. It seems like a person can always use a bigger smoker, and you just went in with the best option right away, congrats! The Auber and permanent probe are the bomb. I just installed my permanent probe last weekend, and it is awesome. I should have done this months ago.
Just a great tip. Tony (DivotMaker) suggests a 1 inch nylon spacer so you get a probe only appearance in the actual smoker. I didn't do this initially, and the probe plus nylon threading was just too much into the smoker, where I could see it interfering with my upper rack. I modified it with the nylon spacer, and it is a great improvement, with more room for my ribs.
