We just had this debate in another thread but I'll recap
If you read through the manual it doesn't really stipulate (other than not going over 10k without a change) what the frequency should be. Talking with my dealership at my last oil change a couple of weeks ago the service writer said follow the truck monitoring system as it takes into account all the factors like idle time, drive time, towing...you get the idea.
I'm an ex-mechanic and I still run by the dated rules of every 5000km on fossil oil and every 10k on synthetic. However with todays advances in motor oil the old 5 and 10 are actually outdated and overkill.
So I guess the simplified answer is to follow the on board monitoring system but never go over 10k without changing the oil.
