If ya want to keep it simple, 15w40 HD oil for the engine (whatever is cheap, or the coolest lookin bottle), and the afore mentioned NAPA GL-1 for trans, transfer, and all 3 diffs. I don't know about your budget, but as far as I'm concerned the capacities of these trucks are too much for $$...
For GL1 (pure mineral oil / no EP additives): NAPA 65-205 for 5 gallon pail, and I think there is another, NAPA 65-201 for 1 gallon jug.
Good enough for me, though I wonder who else uses this stuff besides MV owners, and farmers with old tractors. I know, who cares?
