I lucked out, I just turn the pan a quater turn and it fits. I guess that you could saw aome of the handle off if needed. As far as how well it smokes, I just load it with pre-soaked wood chuncks and it smokes for hours.
I know this responce may be a little late but here it is anyway. I have the same smoker and I tossed the little cast iron box away and replaced it with a 10" cast iron skillet, works great, and you can put more wood chunks into it. :)
Thanks for the greetings. Glad I found this site and joined. I am planning to cook up some pulled pork next weekend, and have been reading about it. Will let you know how it turns out. Thanks again. Mopandukey
