I believe the oil is set to 10,000 miles and the fuel filter is 15,000. there is no way to change it without buying some software. I read that you can change those settings with EFI Live, but I am not 100% on that. If you have access to a tech II maybe that could do it too.
Does your truck have the oil life monitoring system? If so, it is not a set mileage. I believe it reads engine revolutions and triggers at an appropriate time. I thought fuel filter was based upon pressure drop but I really don't know on that one.
