I have a masterbuilt pro dual fuel two door smoker. I use it as a gasser. I have done the door seal mod as well as a cast iron chip pan and needle valve. Not liking adding chips all the time, so im going with either amnts and put it in the smoker, or doing a mailbox mod and going with the amnps. I have 4" round vents on both side of the smoker to make the mailbox mod easier. Which mod would you do, and why? Thank in advance for the advice....
