Actually, to me it looks like you cannot use propane (or electric) to heat/cook/hold your sauce. Anything in the hand-in box going to the judges must not have been heated/cooked/held by propane or electric generated heat.
From the KCBS Rules:
"5. Fires shall be of wood, wood pellets or charcoal. Gas and electric
heat sources shall not be permitted for cooking or
holding. Propane or electric is permitted as fire starters,
provided that the competition meat is not in/on the cooking
device. Electrical accessories such as spits, augers, or forced
draft are permitted. No open pits or holes are permitted,
except at the election of the contest organizer. Fires shall not
be built on the ground."
Just my opinion based on the written rules.
