Should also add ......top vent open, 2 bottoms closed, fan connected with sink drain on the 3rd vent and fan plugged in at start. It ramps up to temp and holds great. Thinking of building burner vent for fan.

Thanks! Those are the defaults, which I tinkered with way back when. I think I'm going to revert to those settings for my next smoke and see if it improves my stability. It's working well now, but still seeing some fluctuation.
