Nice truck! If you're driving it currently make sure you have a jack to go with your spare. That's an inside joke for a previous responder. Seriously, no pun intended, if you have electrical issues at hand I'd be sure I had a fire extinguisher in the truck/at hand. Also tools to disconnect a battery quickly if needed. It'd be a shame for an electrical issue/fire to crop up and burn things up. Seen too many close calls with old wiring.
