you get optimum fuel milage when your motor reaches "stioch" or 14.7to1 air to fuel ratio.
with modern fuel management and automatic transmissions the onboard computer makes the most of a given load and speed situation.
your mileage to a point will be the same until your reach peak efficency. after that, the faster you go the more fuel you will use.
so your observation about rpm and torque makes sense.
that is assuming everything is in working order in your truck.
