Hey guys, I have owned a Brinkman Vertical for a few years and have turned out some pretty good Q on it. Unfortunately, there is no tuning allowed on this thing. I drilled some holes in the coal pan to get a better burn, but that is all. Anything else I can do to help keep a constant temp? I don't use the water pan anymore since it doesn't seem to change anything except taking longer to get to temp. Edit: I wanted to add that the one I have doesn't have the vents on the sides like the new one and has three shelves instead of two. Nice thing is I can just barely get a full rack of baby backs on each rack diagonally.
