Maintenance Schedule

3,000 mile oil changes are pointless IMO. I go by the GM oil life system: http://www.performanceoiltechnology.com/changing-oils_changing_drain_intervals.htm They spent a good amount of time and money engineering the truck to know when it needs an oil changel, I'm not going to second guess it or ask the local oil change shop what they think is best for my truck (or rather their profit margin). Back of the manual has other maintenance intervals as well. IIRC the first one is transfer case fluid change at 50k, but if you have a 2wd it might be 100k for the first scheduled service.
