What's in your toolbox?

[MRUSA14]

I carry most of the above plus a Dremel kit, electrical crimper and attachments, soldering kit, and pop-riveter. Don’t forget the duct tape.

I have pretty much everything listed except the Dremel-never owned one. I also have a 30 inch tire iron. It lets me slide a tire off the hub without lifting it. I have a set of DOT warning triangles, two reflective vests and two traffic cones for roadside protection. I have two foot long chunks of split loom in various sizes to protect hoses and harnesses from rubbing against other things and a tube of NYK 77. That's a product that prevents corrosion in electrical connections.
What I don't have is combination wrenches or ratcheting box ends. Instead I have a set of open end and another set of box end wrenches. If I have to hold a bolt head while turning a nut I need two wrenches the same size. This way, I'm good. I find ratcheting box wrenches that are thin enough and strong enough to be useful come from Snap-on, Matco or Mac Tools and cost A LOT. I had a set of Craftsman ratcheting box wrenches...and gave them away.

I carry a 4 drawer tool box pretty full with a soft sided bag with more hand tools, wiring equip, fuses, torque wrench, jack, wheel nut sockets, 18v rattle hammer, most of the tools are for changing tires on our flat bed trailer which i have to do several times.
