I set mine at 200 for all night, then 250 the next morning to finish usually about noon the next day.
I think 225 from about 4 or 5 PM to 6 AM should work. It will finish cooking in the foil/cooler and it will hold for 4 hours & be moist & tender & warm to carve/pull.
I did 3 one night & the drip pan overflowed, damn big mess.
