UPDATE

There's now a Res-Q-Me hanging from the rearview mirror. The Lifehammer is now in the glove compartment until I get a new mounting bracket.

There's a large FAK under the passenger seat. (Well, large by commercial standards -- here it's more like "a good start". )

And I now have two Photons in addition to the Maglite Solitaire.

I put an AMK Mini-FAK and a Spark-Lite & Tinder in my bag, and I think I'm set for the scenario I outlined in the original post.

Thank you ALL for your inputs!
