Thanks for sharing cooler sizes.We used a pickup bed completely full of coolers to haul most of two moose from northern BC to S. Dakota. The meat was hung and cooled, then boned out, before we left the camp. We used a little ice (10 lbs per cooler - replaced once) and everything was fine when we got home around 40 hours after leaving. We drove through temps up to 72 degrees but most of the drive we were at 60 or less.
Our coolers:
2x 150qt
3x 120qt
1x 72 qt
