3 hours of hickory smoke at 250
then make a foil pocket fill with apple juice, submerge ribs, back in the smoker for 2 hours.
then take them out of foil place back on the racks and smoke for another hour at 225 brushing on BBQ periodically
when they're done the bones will be sticking out like bear claws and the meat should come off the bone cleanly without falling off
I have done it this way both in a smoker and on BBQ just have to pay close attention to temp
