2008 Ford F-450 Super Duty XL 4dr Crew Cab LB DRW (6.4L 8cyl Turbodiesel 6M)
I've got just over 20,000 miles. The fuel mileage is pathetic at 8.4 mpg average (about 7 towing and 9.5 not). It's been in the shop to many times to count. 3 radiators, water pump, idler pulleys, thermistats, wheel bearing, etc. It ruined our last vacation by being stranded in a tiny desert town for several days.
Pulls well, turns good for a big truck. High towing capacity.
Dump the Navistar engine and put in a Mercedes. Teach the factory guys how to install components!
