My truck's 360 cid V8 doesn't feel the compressor, I can run it all I want.
Trucks are not like cars, their engines are designed to do one thing: Pull load.
And that is where 90% of the engine's energy goes, into pulling the load.
Even the best aerodynamics make small effect on a truck's fuel economy.

Why those square yellow brick school buses wouldn't get better fuel mileage if their front ends were more aerodynamic, their engines are pulling so many thousands of pounds of load that even the aerodynamics of a billboard hardly affect its fuel economy.

The only thing that affects its fuel mileage are speed variations, and their amount and intensity... The few things that frustrate me the most, other than folks tailgating, are drivers cutting me off, getting in the space in front of the truck without thought as to why that space exists other than they're trying to get to the proverbial finish line.

When a truck is following the car in front with a 4-6 second distance...
DON'T cut into the empty space in front of it!
It is the truck driver's "safe following distance."
It exists as a buffer, to help in case of sudden stops.
Not because it saves fuel, but because it takes that long TO stop!

When a truck is SLOWLY coasting to a stop light ...
DON'T cut into the empty space in front of it!
Doing so may force that truck to stop completely.
A truck coming to a complete stop wastes a tremendous amount of fuel re-accelerating.

My truck's mpg hovers between 10 and 11 miles per gallon.
