Fuel mileage 2009 F-450 6.4L
I average 9.3 mpg empty regardless of speed and towing 15,000 lbs it gets 4.5 mpg. HD(?) 16,500 GVW 4.88 gears. Is this normal?

The truck also had $20k+ in warranty work in 18 months.
I can't even fathom how much has been spent on this truck.
I've never had a need or any interest in owning a diesel PU.
