The reason there's not more water in that bag is that it's not a bag that's intended to REPLACE what's in vehicles already, it's used pretty much always for local excursions, as an overnight kit, or just to have a mix of gear that I actually use.

The genesis of this kit came a few years ago when we got a fire call for "wires" which is one of the worst calls you can get.

You sit in the truck, for HOURS, watching the wires spark, hum and eventually grow silent and deadly. Eventually the utility shows up and turns off the power. It was on one of those calls, at 2AM on a sunday morning, where I was wishing I had a book. And a granola bar. So I tossed that into a bag.

Then, maybe a few months later, I was at a body recovery job that went on for days on a cold January. The side sonar crew found it and the divers went in after dark, pulled him up and all I had to do was drive the boat trailer back after all was done. Well it started to snow, and I didn't have a hat and winter gloves, just turnout gear, which was silly...

Anyway, everything in the bag is reactive to situations I've actually been in. The only thing that's really a candidate for removal at this point is the "D" batteries, which are heavy and only used to cover someone else's ass when their maglight goes bad. I'm perhaps not as altrusitic as I used to be.

One thing that might get added in the future is some sort of something to sit on, but I'm really at a loss as to what I can find that's LIGHT, TINY when folded but strong enough to hold my fat 200 lb butt. Something in titanium, perhaps with shock-corded 3/8" poles and a nylon seat, under 2 lbs total weight.
