What kind of mileage did you get with that engine?

When it was running that is. :)

I've never manually calculated mileage to date, but based on the truck
computer readings, mileage is roughly as follows:

Highway driving, up to 65 mph, unloaded and not towing: 18-19 mpg.
Highway driving 65-75 mph, unloaded and not towing: 17-18 mpg.

General around town driving: 16 mpg

Highway towing 5000 lbs: 15-15.5 mpg.
Highway towing - 12,500 lbs. (Fifth wheel) 10.8-11.3 mpg.

I don't have a heavy foot and rarely "tromp on it".

I've noticed that since winter arrived the mileage has dropped by 1 or 2
mpg. I understand that this is due to the winter blend of diesel fuel used
around here that contains anti-gelling additives and also lowers the amount
of btu's in the fuel.

The technicians that worked on the truck last month in Georgia told me that
the 6.0L can put out another 100 horsepower with a performance chip. I'll
never bother with it since when it runs it has all the power I need.
