Being that I’ll most likely be building and changing my van for awhile after I get out on the road, I’ll probably end up with a few more tools to begin with. But, that was my thinking, too - a basic tool set, a ratchet set, and a drill.
The smoke/carbon monoxide tester is a definite must. (As is the fire extinguisher.) Since learning about van life, I’ve read too many horror stories in Europe about folks living/sleeping in their vehicles somewhere and being either killed or put to sleep by carbon monoxide by thieves. If that catches on in America… Granted, it’s an essential piece of safety equipment anyway but, given the tendencies of the world today, I think it’s absolutely vital for van lifers.
Emergency food, water, and ways to keep warm and cook. That’s exactly what I was thinking. I was just wondering if there was anything I hadn’t thought of since I’m not actually in a van yet. Nice to know I’m on the right track at least.
The only thing I would add to what you said @Van_Dweller is Grapefruit Seed Extract (cheap and anti-everything: bacterial, fungal, etc.,) It heals wounds really quick. And also colloidal silver. I make my own and take it at the first sign of getting sick. It knocks it out immediately and, as a result, I think I’ve been sick twice in the last five years and that was because I didn’t have my colloidal silver kit with me.
