I just increased the mpg on my F450 from 10 to 13 mpg. I started to drive more steady at 65 mph, changed oil to Rotella, installed new type of turbo compressor wheel on my early 99 model and since I had heavy load, I pumped the wheels to 90psi.
The high tire pressure has some drawback. Comfort in the truck was never good, but now the truck become extremely sensitive to pavement cracks. Couple of times road crown gave me wet back.

The 65 MPH is likely what's causing the majority of your fuel savings. Inflating tires that high is like stepping over dollars to save pennies.
