Can I weigh in on this?
About two or three years ago, I looked ino this.
The official test for coolers, is to put block hard ice in the cooler, with a wired thermometer, placed in a 90 degree room.
They don't open the cooler, and when it goes to below 32 degrees, test over.
Under that arrangement, there are plenty of 5 or 6 day coolers out there.
I wound up with a Coleman Marine 6 day cooler. At about a 5th of the cost.
Only advantage I really see, is that BEARS can't get into a Yetti to drink all of your beer...
It's Bear proof.
