Made it the rest of the way home the next day without any new issues. 63-65 on 75MPH highways isn't fun, but if that was the worst of it, I'd take it.
Best feeling in the world to pull Hazel into my own driveway in one piece!!!
I can't really say that any of the problems were due to negligence on my part, or wear and tear of an old truck. Maybe not enough attention to torque specs... The u-joint that exploded only had 12K miles when we started this adventure, and had been greased. I did know that the fuel inlet on the fuel pump was at a bad angle, but it had been working fine. The rest was pretty much fasteners getting loose, aside from the cheap a$$ wiper blades.
I'm seriously considering retiring Hazel from long roadtrip duty though. I don't think my nerves can handle another "vacation" like this one
