Yeah, "tune ups" are kinda not needed on our trucks. There's a few things that come due around 100,000 miles, such as the trans. fluid and filter, serpentine belt, and spark plugs, but other than that, there's not a whole lot to do. Just read the service section of your owner's manual. It provides a GUIDELINE for when to do service. I cap'd "guideline" because it all depends on your situation. They will tell you to do more than is required, because the service manual thinks that you're ignorant, and that you don't know how to tell when certian things need replacing. If you are ignorant, then follow it. If not, then you know that you don't have to change your air filter every 10,000 miles. Just change it when it gets stopped up.
