Regarding food, toilet paper, and all other items, you need to carry or break down items into hiker sized portions like, a half dozen eggs in a box, a stick of butter (instead of a pound or whole box), potatoes and onions and apples and whatever by the pound (not by the bag), small bags of stuff like rice, lots of ramen, lipton noodles in small packages, single rolls of toilet paper (someone already mentioned that), small portions of sugar and salt, tuna in the pouch, small cans of any type foods (hiker sized), small boxes of spagetti, zip lock bags (pint and quart size), hiker size portions of anything, frozen meats (individual size portions), cheeze (one pound blocks).
Dehydrated foods (fruits of all kind, beef jerky, etc). Hikers love them because they are a tremendous weight savings.
So think small sized portions of items just for one person, which can be carried.
See you out there. :cheers
