Hi Dan and welcome to the site,
I believe I read where you said you were "new to diesels", if this is the case get a spare CPS (cam position sensor) and keep a 10mm socket and ratchet with you. The CPS is a part that can go out with no warning, the truck just shuts down and that's it until it is replaced, sometimes they give warnings they are going such as shuting down but restarting when the truck has sat for a while. One indication is trying to turn the truck over and the tach doesn't move.
It is relatively easy to change, the part is located in the front of the engine towards the bottom and held in place with a bracket and 10mm bolt. Can be changed in 10-15 minutes. Check on ebay for them or International dealership in you area:
Camshaft Position Sensor (CPS)
(Ford) F6TZ-12K073-A 94-96
(Ford) F7TZ-12K073-A 97+
(International) 1821720C99 (below engine 375548)
(International) 1825899C93 (above engine 375548)
Also, a spare fuel filter is a good idea just in case you run across some bad diesel along the way or some crud in your tank decides to break free and clog things up. These are not that common but can happen.
One other thing that may occur is a valve cover gasket may short out. It is used as a wire harness and the connectors on the inside can short out. The symptom of this is the truck will run HORRIBLY as only half of the engine is working usually passenger side for some reason. It too is a relatively quick and inexpensive fix and I apologize but I can't find my part numbers for this, maybe someone else can chime in.
Now I don't want to make it sound like you are in for one repair after another, but these are just some things that go out on the trucks. I have a 95 with 313K miles on it daily driver and we take it on our long trips, that is how much confidence I have with it. The things I mentioned above have happened to me, (thank God not all at once), so I am just passing the experience along.
Enjoy the truck, keep the oil changed, and it will serve you for awhile!
Take care and don't hesitate to ask questions,
