Granted if you wanted to haul a FROZEN packaged or Deboned harvest of any kind across the country, then the ice test is relevant.
First point... The coolers are frozen 24 hours before the test starts. Not many people can fit a 120 qrt cooler in their freezer.
2 point. The cooler can only be opened for less than 10 seconds over any 24 hour period. Long enough to snap a pic.
3 point. My cooler lasted 9 days
4th point .. if you fill a huge cooler packed tight with ice... You can't lift it, So ..
Norms advice is the best yet, get one with a set of wheels and a long handle
For the sake of the conversation tho, I froze my 60L in a walk in freezer, and then packed it at the butchers with a deer that was ground and very well frozen. It was in the cooler 5 days in the back of my truck in October before I made space in the freezer for it, and it could have gone much longer. But again, I couldn't lift the damned thing by myself
