not much to add, but I find leaving the kitchen sink at home, and keeping it simple makes the camping experience much more enjoyable.
I try not to bring more than 2 days of most foods with me. Shopping along the way for an hour every couple of days is okay. I need ice anyway.
Bringing a week's worth of food, unless I'm headed way out, is a waste of space. I also tend to one pot meals, and even frozen tv dinners. Having a microwave makes meal prep a lot easier, and clean up easier as well.
