The odometer on my 2014 Expedition recently rolled to 200,000 miles. I love this vehicle and want to make it to 300,000 miles. What preventive maintenance would you suggest to help me get there? Also, suggestions for epic road trips on the East Coast to rack up the mileage are welcome. Recent work completed (and scheduled soon) includes replacing spark plugs and ignition coils, new tires, oil change, ball joint and control arm replacement. What else should I be considering at this point?
