Thanks again for all of the help. Polar Bear 24 ordered and should arrive today. Packing is going to be the next challenge. The company I am going to order all/most of the meat from sends it already frozen and I don't think I want to thaw and re-freeze it. So, I will probably have to pack most everything into the cooler already frozen and there will likely be some air pockets. I might be able to fill the larger spaces with some of the looser items such as shrimp and maybe even throw in a couple of packs of frozen veggies. I guess it will be like a 3D jigsaw puzzle. My only worry is fitting everything packed back into the cooler if the TSA makes me empty it. Is it better to take two not completely full coolers or a single cooler with everything crammed in? Definitely first world problems...
