I agree with everyone on having a stove to cook with when you don't want to start messing with a fire if it's late or it has been raining.
On a fire, hobo packs work well. Double or triple foil wrap some pork, peppers, onions, potatoes, with spices and some beer, place on coals, ignore for 45 minutes. More or less time depending on size cut.
Make sure you have a way to process firewood, whether saw (simple bow saw works well), hatchet or knife to baton (I find safer than hatchet).
Having a tarp to set for shade or a rain cover makes cooking etc better.
Can never have enough flashlights/batteries. Or lighters and matches.
Ferro rods are great but to catch the spark you need to be prepared with dry fluffy material (jute rope) or cotton balls/lint with vaseline. Then you'll be the hero.
It's imporant to sleep comfortably however you prefer. Same as making sure to have clean clothing most of the time
Make sure to have a first aid kit with more than bandaids. Some pain meds,(tylenol, advil), benadryl, pepto and imodium. Antibiotic ointment plus gauze for bigger boo-boos. Rinse well with clean water.
Only fresh meats, dairy and beer needs ice. Bread/ tortillas, salami, block cheese, nuts, peanut butter, fresh eggs depending, hot dogs, beans, rice, fruit, veggies, whisky don't.
