Buying a Masterbuilt 30" vert. propane smoker. I had viewed a model from HD and it said it was both a charcoal and propane smoker. I looked at the one I ordered and it does not mention that it is a dual fuel smoker. It is the same size and looks the same, is there such a thing? Or does it even matter? I just started browsing this forum and I think I am going to enjoy learning about all this. I had thought for years that I wanted to someday own a Traeger. They are made close by. One thing I have read in some reviews of this model that is not clear to me is in regards to the regulator. Any further clarification on that? Thanks for any info.....
