This is an interesting thread. Ford motors have a great reputation for longevity. I have drove a couple off 150s in years past with over 300,000 miles with very little problems. Probably a few 04s with over 100,000 Im guessing.
our parts delivery truck, 04 216,000 not one problem. the truck doesn't hall heavy loads but it does a lot of stop and go and short trips. we are looking to replace it with a transit connect, and i am thinking of buying it for my self
'04 XLT HD extended cab, 140,000 miles, Full size (8') bed, everything is original stock. I have and will fill the bed to the side rails to haul rock, gravel, dirt, and even 10' logs (to the have milled into lumber). This truck is no stranger to the county land fill. I have been known to hook up dump trailers but not often.
I also do all my own maintenance and keep an accurate record of total cost of ownership.
This truck works for a living. Former Fords usually go over 200,000 miles before the records start to show an increase in ownership costs. At that time I start to consider a new truck.
No I am not Ford tech, or work for any vehicle service company. I am just a systems engineer who likes to work with my hands for exercise and hobby activities.
