nsxbill,
You might want to open the vent more if you're doing some jerky or if you notice moisture build up.  Sometimes on rare occasion I have had the moisture seeping at the door which is a big no-no cause of the electronics below.
Like fuzzy says, its mostly for temp control in my observation.  I seldom open it very wide, like you, maybe an eighth.  Just enough to keep the smoke from coming back up the generator.  I find that I generally need it closed to get the cabinet temp to where I want it to cook at.

I agree with all above, remove the moisture to get good bark.

When I do butts, it's open 1/2 to 3/4 unless it's Indiana-winter-time.

Another thing to consider is: Are you cookin' 1 piece or a smoker full of 40#.

Ya think next time I check into a hotel & they ask "Smoking or Non?" they would mind?
