Once again,as Ribdog says,a good tight double wrap, in HD foil, is often used by comp teams,taking 4-6, eight-nine lb butts to the cambro, to hold ,to make our boxes.
Having worked with vendors,they may take the 8,10,12,16- ten pound butts,straight from the cooker to a Coleman 120 qt cooler.
They'll probably hold 6-8 hrs,and pull them out as needed.
Foil is an extra / ? expensive step that may not be needed.
They stop at the car wash and spray the racks,pans,cooler,etc,on the way home.
Hope this helps a little
