Let me throw my 2ยข in too, Rick - DON'T DO IT! OK, got that out of my system...whew, I feel better! Seriously, it is NOT necessary. There are too many people out there, on some other forums, that are never happy with something that works incredibly well, and feel the need to "mod" anything they get! Unless you drill some big air holes in the bottom (which, btw, will void your 3-year warranty), the AMNPS won't work. Besides, chunks is the way to go with these smokers! Great consistency, and it takes so little, a bag of chunks will last a LONG time!
