We had a successful transit also. I was very pleased. Although our run was much shorter than your from the left coast.

I was still a doubting Thomas before our trip so I put all of our food items in my dry bag and then did 4 days in the freezer. The morning of our departure I put the dry bag in the cooler stuffed a few carry on items on top of it for the trip. Nothing had even begun to de-thaw when we arrived. Very impressed with this cooler.
