Another possibility is to cut your temperature. Fuel intake is not linear with temperature. If I run my offset at 275*, I can be adding fuel every 3 hours or so, but if I lower it to 200*, I can go a good 10 hours. If I'm doing butts on my offset, I'll put them in at night before bed, then I can get a good night's sleep, and add fuel and crank up the temp in the morning if necessary. Butts will be done early afternoon, wrap in foil for a couple hours and pull for dinner.
