I know what I missed from that list.... You could purchase this cause I am quite sure you wouldn't want to borrow it. You need the orange plastic potty trowel. (although someone said they have different colors I have never seen any but orange.) And if the gram weenie in your inner child needs soothing you can even cut the handle down. Although I understand it makes it harder to dig with. In so far as the TP is concerned, remove the cardboard core from a roll at home and pull out what you think you will need from the center. No need to rewind or buy little camping packs for the price of an entire year's supply.
The rest of the roll goes in your gear closet to be forgotten about the next time you need to resupply until you have destroyed another whole roll making mom oh so happy.
