Buy a 125 qt cooler, make sure it is cold when you put your meat into it, out ice in at least a day before you are going to put the meat in. Try to cool the meat before you put it into the cooler, then drain the water out of the cooler, put in some fresh ice, then the meat and ice on the top to the top. Do not open the cooler till you get home. You didn't say if you had access to a cooler but if you do, cold meat going into a cold cooler is the way to go.
