Hey all, I am wanting to put together a tool kit to store in the cab of my truck. (2006 2.3 supercab xlt 2wd) I was thinking of using a canvas tool roll. What I am wanting to know is what are the most common sizes of wrenches I would need. I'm not a mechanic but I want to have the tools on hand to fix problems if they arise. already in the truck is a flashlight, fuses, rags, extra oil, a bit driver with extra bits, and regular pliers. I'm mainly looking for a minimaly sized kit with the maximum amount of use. Thanks guys. And I hope this is in the right forum.
