I have a typical survival kit in the truck all the time -- in my little haversack/messenger bag whatever ya wanna call it - flint and steel, snare wire, fishing kit, water tabs, cup, etc. I also have a small alcohol stove, metal pot, tea/bullion/sugar in the same box that's in.
I've been broken down on the side of the road (dirt road nobody drives on), stuck in the woods hurt, and a few other things before. No cell phone at the time, probably bad reception there anyhow. I've done SERE training too, so have spent time surviving for real, even though there was a safety net at the end if required.
A woods trip automatically comes with the standard survival stuff if I'm along; fire starting (usually an 18th c. flint and steel with tinder set -- and yeah. I can use it with a broke hand or cold or rain - been there, done that, got stitches) water purifier (or ability to strain & boil it) with ability to tote water, fishing gear, axe & knife, some kind of shelter, some kind of short and longer term food. I keep some method of signaling for help with me too.
If Armageddon comes, we load all my firearms, bows, edged weapons, ammo and and wool blankets, along with the food we have, in the truck and go to my father in law's farm in deep south GA. One tank of gas'll get us there and then some. Between the food they keep put up, game on the farm, and ability to support ourselves from the farm, we'll be OK.
If I'm lucky, I can hit the feed and seed on the way outta town and stock up on corn and a few other things. I already have a supply of heirloom seeds saved up that will go with me.
