Other than oil & filter, I would think tire rotation would be required. At 7,500 miles your suppose to change the rear end fluid - See below if it meets your driving habits:
Replace VTM-4 rear differential fluid: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (shear) stress to fluid or frequently fully loaded. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
