When we have vended at rodeo's and the like, we fire up the Spice for cooking and dial in the Backwoods for keeping the food warm. Can easily keep the backwoods at 140 degrees. Once the cooking is done on the Spice, we like to put the pulled pork in pans on teh spice to keep the smoke going.
Had to explain all of this to the HD when they inspected us the first time and they had no problems as long as we kept the food in the safe zones.
We cook our baked beans in roasters and have not been inspected during their use, will have to find out if those are ok around here.
