May be some duplication ( I just pasted with no editing) but it should give you some ideas based on what you will be driving through. You'll need tools too
To take for sure:
-----------------
Upper and lower radiator hoses - prone to getting hit by rocks
Epoxy for radiator (Waterweld)
Serpentine Belt - prone to getting hit by rocks
Fuel Injector cleaner - in case of bad fuel
CV Axle, R & L seals - CV boot can shred, axle can break
Spare Keys - forgetful...
Tire fix kit - most likely failure
U-Joints - front & rear
brake pads - wear part, we'll be driving 50k+ miles
fuses
Filters:
--------
Air filter
Fuel filter
Oil Filter
Fluids:
-------
Gear Oil
Engine Oil
Brake Fluid
touch up paint
Leave at home:
--------------

Water Pump
OME bushings
Alternator
Idler Pullies 1,2,3
Cigarette lighter jumper cable (Useless?)
Intake Gasket - have to remove the intake to do anything to the engine...
Cabin Filter
