Heck, a couple of years ago we went to Flagstaff - 11 hrs, total - with a couple of frozen lasagnas. We were going to eat them that night so we decided to let them thaw on the way. We just wrapped in towels to keep the condensate from getting on everything thinking that they would be good and ready when we got there. We also stuck in a couple of big packages of lunch meat to keep them chilled.
Keep in mind, all this was wrapped in some towels. No fancy cooler, no ice, nothing. Just some old bath towels ... and stuck in the trunk. The outside temp hovered around 55 F most of the trip.
When we got there not only were the lasagnas still frozen rock hard, but everything we'd put in with them was frozen solid, too!
If the meat is frozen (deep freeze), just wrap them in a couple of towels then stuff them in a cooler full of wadded up dry towels. Don't worry about ice, or even those fancy ice packs. Chances are they will still be completely frozen when you arrive.
