Don't know about Texicans, but down here, we usually watch.

1. medium Knipex pliers, Alligator pattern
2. 6 way screwdriver with small hex on the small bit end
(otherwise its a fake 6 way, really a 5 way)
3-6. K-D flex head 3/8 ratchet, 8,10,12,14mm sockets
7-8. 6"&10" adj knucklebusters
9-10. 2" wobble, & 8" 3/8 extensions
11. 12mm combo gearwrench
12. small pry bar

I also carry a Leatherman Wave and LED penlight at all times, plus a Kershaw and a Swiss Army knife money clip style, and a keychain 4 bit folding screwdriver, and whatever tool I stuck in my back pocket and forgot to rebox, usually a 12mm combo wrench. And I move BOTH tool bags from car to car, and there's not room/time to list that one. And you can get way more stuff than a 12pack in a small tool bag. You can pull the engine with what I carry in my small bag, upper bellhousing bolts and crank pulley included, and the big bag has the hoist...
