I drove my van into Death Valley and parked at a campground. The next day it would not start. It turned over nicely, but would not fire. What would cause that? High pressure oil leak? FICM? ICP sensor? 5 minutes on the Ford computer showed it to be the EGR valve stuck open, but how to isolate that while on the road? If I had an EGR valve I could have changed it in a couple of hours, but I would have been throwing parts at it and hoping. How many other parts would I have changed before I changed the EGR valve?
AAA has towed my van to shops that can work on 6.0's, and the AAA card is my best part to carry.
I think this is the most important thing, being able to diagnose the problem and decide on plan of action.
Scanguage with all the extra params/xguage programmed AND a knowledge of what they should be is a good start. Common items like FICM voltage and ICP will tell you a lot just while cranking on a non start. Other items like cam/crank sync won't give you a correct reading until engine is running on a scanguage. So knowing things like this is key to diagnosing the problem correctly.
If you have a scanguage, the below tread has a lot of info and (document to print and keep with your ford handbook in the van)
. It give you the normal readings for each censor.

But it does not state if scanguage can give you an accurate reading on crank. That's something you need to play & learn.
The below thread is also vital, worth learning the key items in it, there is also a word doc of it somewhere that may be worth printing out.

Autoenginuity and a laptop is the other item that will give you a lot more info that scanguage, if you want to spend $$$.
Also, remember that with 2 full starter batteries, you don't get that many cranks before they are both dead, so a way to charge the starters from the house OR crank off the house batteries will help a lot.
In saying all that, the only ford 6.0 specific part I keep are O rings for the fuel filters, as I've had the O ring on the top filter fail on me more than once. You can carry all the spare parts you like, but if you can't diagnose the problem correctly it's completely worthless having them.
