Jason;
Should all of my questions be so easy to answer. In fact, I didn’t answer it, you did when you said that you didn’t cross-stack the dough boxes. That’s the reason why the dough “blew” during the night. Colder dough isn’t the answer, the options that you have available if you don’t have room to cross-stack is to use an end to end off-set stacking pattern (You’ve got to allow for ventilation of heat out of the boxes, or you see what happens. The other option is to oil the dough balls and drop them into individual plastic food bags, twist the open end into a pony tail to close then tuck the pony tail (DO NOT TIE) under the dough ball as you place it onto an aluminum sheet pan, then place directly into your cooler in a pan rack with a 5" spacing between the shelf brackets. With this method there is no need to cross-stack. A variation of this method is to place the dough balls directly onto a very lightly oiled sheet pan and place then in the rack in the cooler allowing then to remain uncovered for 3-hours, then slip a large plastic bag over each pan of dough balls, folding the bottom opening of the bag up over the leading edge of the dough balls and then pull the top opening of the bag down to completely cover the front of the pan and tuck the edges under the sheet pan to secure.
If you have any questions, please free free to contact me directly at 785-537-1037 and I’ll be glad to walk you through it.
