it took about 8 hours for a 6# piece. well worth it. It stalled out at about 169Âº for alittle bit. It cooked for about 6 hours total and then wrapped in a towel and put it in a cooler. Just pulled it out of the cooler after about 1 1/2 -2 hours and picked it apart with a fork. I have been able to have the temps steady for an hour or 2, but nothing to where i can go to sleep for hours. I don't know how some of you guys can do all nighters and keep temps all night. Anywho, I have sandwiches for at least a week.
