Next to the smoker this tool is 2nd --
Dave is correct we prep our meat full SS pan 1/2 full of ice cover with foil and place meat in Cambro -- 8 to 10 hours later still ice.
Crash is correct once your meat hit's mark -- Cambro up to 4 hours.
A ice chest works OK but no as convenient.
PS this is a pro cater setup -- double top and bottom does not separate and is on oversized wheels
