On the topic of a cooler, I've got this one from Coleman.

The white exterior is great as it absorbs less heat. I have easily gone 5 days summer camping with it as my only cooler with drinks and food, so being opened frequently. Some tips I have is to swap some beers out for something like Gatorade and freeze them. As well, for some foods you know won't be needed till day 3 or later, freeze them. Anything else you add, always get it as cold as you can before putting it in the cooler (fridge night before or a bag of ice and discard before you leave for the trip). I use those flat blue freezer packs as they fit well between items and can layer em.
The super expensive coolers ain't worth it.
