2008 Ford F-450 Super Duty XL 4dr Crew Cab LB DRW (6.4L 8cyl Turbodiesel 6M)
When it works it is a good truck. In '07 hauling horses and 40 footer it stranded us on the road in Oklahoma. Two weeks, two dealers later it was supposedly fixed. Broke again on the way home. Right now it is in shop in North Carolina. Stranded again on road in Nebraska. Fixed then broke again in NC. Replace injector 1 three times, and elect module once. This truck has been towed to shop four times. When we get it back .... sold.
The warranty and road side assistance.
Build one that can keep going. Train the mechanics to fix it right first time. Parts take 2-3 days to get in. Better mileage get 6-7 when towing.
