Woke up this am to start my first smoke, prepped my butts yesterday. Got the smoker fired up around 4:30 am, butts broke the 140 degree mark in just under two hours. My question is...... Considering that this is a propane fires smoker, does the timing vary greatly due to the btu's from the gas? Oh and what do you do when the water bowl dries up? Dumb question I know.
