Grizz, welcome! I have a #1, and we see this question (and ones like it) a lot. Here's my 2-cents worth... don't try to fix something that isn't broken. Get to know your smoker the way the designers intended it to be used; they did a pretty dang good job! This smoker is designed to use wood in the smoker box due to the cycling of the heating element, and it works great. As you'll see from the posts here, you'll never need more than 6 oz of wood for even the longest cooks.
I've heard good things about the Amaze-n tube, but it's just not needed in these smokers; save it for the gas grill, or whatever. You will find that using these smokers "as designed" just can't be beat. Good luck with your #1, and join us often!
