My BOB/winter kit blends a bit with an emergency tool kit. Especially with the jeep I find that I somehow end up with more tools in the vehicle than I realize.

So tool/car specific stuff, and ignoring the big bag with the usual BOB-style stuff (including mini saw, hatchet, etc) - I have a tool roll of wrenches, and a small bag full of various tools. I really love those small canvas bags you can find at most stores - has held up really well. The bag also has some easy fix-it stuff like zip ties, bailing wire, duct tape, fuses, straps and bungies, siphon hose, etc. Tossed in one of those smaller socket sets from Lowes - seems like I use that a lot. There's also a recovery bag in the jeep with several tire repair options, spare u joint, winch stuff, jumper cables, etc.

Just ordered one of these mini battery jump starter things, supposed to be pretty awesome.

One thing I don't have squared away very well is fluids. I need to find a good way to stash a spill-proof box of various fluids. There's actually a bunch of room under the jeep trunk that's high enough to not get in the way - maybe one day I can rig something up like a bracket for a 30cal can there.

Had bolt-cutters in there but I took them out at some point and never put them back in. Maybe if I got a folding set like yours they'd stash easier.

Also, I need to get and test some burner phone options. I know supposedly you can just keep old phones with no plan stashed away and they'll always dial 911, but I'm thinking maybe something a little more hearty. Guess that's not really a tool though.

A cheap GPS would be nice. The GPS in the jeep has gone bananas and I haven't got it fixed yet, didn't realize how much I started using it once I had it.
