Planning four racks for dinner at 6:00 pm but can'tget home till noon to start. How long can I smoke for great flavor before I switch to grill? Will brine the ribs then use my first batch of "Jeff's Rub". I think I could afford 4 hours in the electric MES. I guess at most 45 - 60 minutes on grill should finish. I plan to use the pork butt cooler concept to get ribs to eating place. Side note. This Thanksgiving tried the wrap in foil and wrap in towels and put in cooler on turkeys. Amazing results. My wife got to use her oven for over an hour and when time to carve the breast increased temp from 151 - 165. Actually had hot turkey this time. I would think ribs would f do the same. On the right track?
