Here's my take. I'm working from the assumption you don't have army truck experience or even big truck experience. Bear with me if I state some things that are obvious.
If you take everything that you might need, you'll take a fully stocked shop van truck. Not really practical. What you take with you are 1) things that are highly likely to be used, and 2) things that are unobtainable locally. I don't take oil, I don't take antifreeze, I don't take anything that I can readily get at O'Reilly. I do take slave cables...
Read the -10 before you go. It's full of useful tidbits like how to turn on the heater (no, it isn't a switch in the cab).
This truck has CTIS. I like CTIS, but it is prone to letting the air out of the tires. Then the truck sits on them, creased, and weakens them. The result is catastrophic failure at highway speed. Inspect your front tires before moving the truck.
Also before moving the truck and without it running, flip the power switch on. If the guage doesn't go to high yellow plan on removing all 4 batteries and installing 2 new ones. Those 4 may be just fine, but the work of charging 4 dead but good batteries will likely fry your alternator.
////EDIT -disregard this : Assess which tank the truck is feeding from. The switch on the dash changes where the guage reads from, but does not change where the truck is feeding from(ask me how I know). That task is managed by a nice little lever hidden to the left rear of the driver's seat. Look, but don't touch. Whichever tank it's feeding from is the only tank you're going to use this trip.//// your post said 929a2 which has dual tanks. 923a2 doesnt.
Add power service or fuel treatment to include antigel of your choice to that tank.
Before moving the truck (if possible) or as soon as you get off post, check the fluids to include the GO levels in all 3 diffs. Top off as needed. Keep in mind it may leak FAST. Check it again in 50 miles.
I'd bring a can of ether from O'Reilly. Leave the on board ether system alone. A 1 sec squirt into the intake stack each morning (while cranking) should be fine.
Keep both hands on the wheel. A blowout will jerk the wheel. Also, make sure the ABS works. If not and you lock the brakes you'll kill the engine and lose power steering and it'll jerk the wheel from your hands and likely flip over. THE 939 SERIES TRUCKS WERE EXTREMELY OVERREPRESENTED in fatalities before ABS was added.
You're going to get a lot of recommendations to have it shipped. My take is that that isn't realistic. You need to be extremely cautious however. It's one thing to risk your own life (and be assured that you are), but 22000 lbs of out of control steel is a danger to anyone around you as well.
