you know, I think the smoke daddy was what I was looking for, but I searched for smoke gun, other terms and I never found it, that thing was the closest one. It seems like it might work ok for doing small things I do have a pretty nice grill, plumbed into the house natural gas. I WANT to just buy a propane smoker and convert it and plumb it in, but the wife won't let me. So with the smoke daddy you just use a hole saw and permanently mount it? its a Jenn Air, basically like this so with the smoke daddy you can run it cold, but can you also run it with the grill on? or is it cold only?
