Ok, I know this has been covered a million times, but humor me and help me out. For my last few smokes I have had a near impossible time maintaining a temp greater than 200. I have a cabelas brand propane smoker that I bought on clearance 3 years ago. I have tried all different combinations of both top and bottom vents, I have varied the water from empty to full and everything in between. I'm about to throw in the towel and buy a new smoker (realistically that is not happening right now) Any other thoughts?
