I'm near 100K and never had to do much to my Expy ,07. Just oil, tires , battery, oil & air filters. Knock on wood, been a great truck. Guess now's time for: fuel filter, belts, plugs. Anyone see a need for other priority service. i'll check FoMo manual too. The brake pads are still good. The updated 07-present brakes are so much better than my '03 Expy.
