I Am a big fan of the polar bear coolers mentioned above. We have owned several for at least 10 years. I checked the 48 can size many times and we like it so much, we take it along even when we don't take food because villa coolers are usually junky.

I can vouch for the quality of the product, ours get used hard. We use them weekly to transport food to or put cabin and it as overflow storage. They hold ice for a weekend if you keep it zipped and out of the sun.
