I run a butt up to 203 wrap in foil, beach towel and put it into a cooler. I keep the thermometer in it and it will stay hot for hours that way. I shoot to have my done a few hours early then it has more time if needed. Otherwise it's in the cooler ready to go. I've pulled it out of the cooler 3 hours later and it's still 180 plus. On a side note we whacked em this morning. My son with one.
