One of us should start a thread on essential tools and their habitat. I need to rethink my set-up, essential tools that stay in the vehicle.
The only Toyota tool that I like is the 2-piece screwdriver. It works better than the OEM brake spoon, iirc. Other Toyota tools are nice, but, I use sockets and box-end wrenches. Of course, I'd love some of the older wood handled screwdrivers, but, Vessel screwdrivers are awesome. I have some 13mm hardware on the truck, and a couple of SAE sockets (I forget what sizes offhand) for hose clamps. My replacement battery cable uses a 5/16-inch bolt, but, I'm not going to carry a 1/2-inch driver, just an adjustable wrench. You'll see a couple of tools for installing a tire plug, and I carry the plugs in the tool roll, the air compressor is in a bag, at present. I carry sandpaper for ignition or electircal, as well as a ball of steel wool, wire brush for cleaning threads, which may have dropped on the driveway or trail. I have a Toyota spark plug wrench that I really should put to use, but, the 13/16 from HF has the rubber cushion in the socket well. Nothing beats that swivel head 1/4-inch ratchet handle for rapid assembly / disassembly, and I carry adapters so I can turn 3/8-inch sockets as well. A breaker bar, stored in a reproduction tool bag, increases the range of the socket set, yet, I typically just use it for oil / gear oil changes, and major service.
