I have two modes of camping. When going to another place and hitting FHU, I tend to eat out, perhaps some basic groceries.
When dry camping at a festival (where I drop my rig there for four months and use it on weekends) I bring a cooler full of frozen foods, milk, fruit, cereal, and some cubed cheese. I also bring plenty of bottled water and Gatorade. All that goes in the proper fridge/freezer compartments (including gel freezer packs). When heading home on Sunday night, remaining stuff goes into the cooler. As an added bonus, the gel packs do a good job at pre-chilling the refrigerator unit, so it hits operating temperature in a few hours rather than overnight.
