Over the last forty or so years, I've found that tools for minor car repairs and fixing flats or keeping air in the tires get more use than anything else. Never have had any real people-problems, although I have a first aid kit. Gun cleaning stuff, and knife/axe sharpening stuff. Motor oil, transmission fluid.
I asked a doctor one time if I could get a prescription for Darvon and Valium. "Why?" he asked. I sez, "Well, if I take you quail hunting and you fall and break a leg, I don't want to have to listen to you scream for the two hours it takes to get to the pavement.
I never saw a guy write so fast, before.
With me when hunting? A box of shells, 4" hunting knife and 3" pocket knife, some rope and a good bit of toilet paper to mark the bushes where Bambi is, so I can come back and find him with "hauling help". If I'm gonna be out all day, maybe some munchies.
The problem in a dang desert is that it can be below freezing at daylight, when it's sitting time. Then, a half-hour or so after sunup when it's time to start walking, it's time to start peeling off clothes. Midday, a teeshirt and shorts is plenty.
So, a day-pack to stuff the "warmies" into.
My main deal to to water-up before I leave camp.
My hunting country is on the east side of the Solitario formation, seen here:

Concentric rings of hills, with a bowl in the central portion. The north-to-south distance is some ten miles.
I mostly work the eastern foothills and the eastern rim. Fun country, if you don't mind cactus, cat-claw, dagger plants and suchlike...
