Simple Tools
Bonus points for keeping them in an Ammo can
I’m not saying you need to bring your whole garage with you every time you go out, but it helps to have a few of the most common tools on hand just in case. In most cases, a pre-built kit from Sears or whatever will do. It’s easier to know what to bring if you work on your own truck (mainly because you know what’s most likely to break).
Even if your truck is in pretty condition, it’s a good idea. I mean, how else would help roadside damsels in distress? Trust me, showing up as a knight in shining Ford armor isn’t going to mean much if you can’t improve the situation.
