You forgot toilet paper. and plastic trash bags (can be used to make a ground still to capture water overnight and mornings. Duct tape as well as superglue and tampons for wound dressings and sealers.I too plan on buggin' in. But, in the toolbox of my truck, I keep, an axe, shovel, saw, hammer, assorted screwdrivers, ratchet sets in S.A.E. and metric, some cheap tarps, rope, and other cordage, some spare bottles of fresh unopened coolant and water to make a 50/50 mix, spare fuel (diesel) and oil filter, oil for one change. As well as a plug kit and compressor. I plan to add some assorted fasteners, never know when screws and nails may be needed. Oh, I keep two of the metal folding chairs also, if no trees are available I can stretch a tarp over them to make a shelter or just sit on them.
