I know the answer is probably different if you are packing food for 2-3 days vs 4-7 days, plus who is with you - just the adults or both adults and 'kids', where kids can range from elementary to high schoolers. Let's say you are planning a 2-3 days trip. Let's say you also have teenagers. What do you pack? I am not sure how long the ice coolers can keep frozen items good. The camper fridge is also not big! Thanks!
