Right now as I write this I've got the following:

Attache bag - day to day goodies, tiny FAK. (BoB #1).
Trunk kit - drybox with survival items, small FAK.
Trunk FAK - football-sized 1st responder grab bag.
Hiking backpack - survival and trail items, small FAK. (BoB #2).
Camping tote - Rubbermaid Action Packer with camping gear.

The attache bag and trunk kit are always with me for travel (work and personal) and local stuff. If I know I'm heading to the boonies I'll throw in my hiking pack and trunk FAK.

If I'm heading to a very remote area where there's hours between towns, well then I will give some serious consideration to taking my camping tote, too.

If it's a run-out-the-door-now (TSHTF) situation I will just grab my two BoBs - the attache bag and backpack.

I'm already in a pretty rural area, but I don't do things much differently heading into a city.
