I'd take a good socket set, screwdrivers and wrench set. I wouldn't haul fluids/oil with me on the way out to pick the truck up, you can get that stuff on that end when you get there. Check the diffs, swivel balls, transmission and transfer case for fluids levels. Overdrive too if it has one. Check or change the engine oil. Check the brake/clutch resorvoir level. Check the radiator level. If that's all good and the brakes are working, the truck runs and steers, none of the magic smoke is leaking out, then I'd hit the road. Make sure you have a spare, lug wrench and jack also before you hit the road.
The few parts I'd like to have with me on the road would be points, condenser and maybe a rotor. I've burned points during drives of a few hundred miles and having a fresh set of points got me running right again. But if you're not comfortable with that stuff or don't have them available then it is what it is. Earplugs are optional. Let us know how it goes.
