I just paid UPS 225.00 to ship my mounted Bison skull from MO to PA ground shipment. I would hate to think what the charge would be for a heavy cooler shipped 2nd day air. Just take turns driving and drive straight through. I Oct I went on a hunt that was a 24 hour drive and we drove straight through both ways, when I go from PA to SC or GA we drive straight through. One person drives, the other sleeps, then switch. That would be your cheapest route to go and all your equipment and meat goes with you.
