I don't know where you been hiding but i like your style!!!
Tom, i started out on that very same smoker, once you learn how to use it, it'll produce some fantastic Q!!
There's really no mod's for that unit, it's basically set it and forget it, get a digital thermo and stop lifting that lid!!
Your so close, i say finish it on the smoker........i personally have a rain coat for mine......
Ya have any questions on that unit shoot me a P.M. i'll be glad to help ya!!
