The key for those of us with big engines is to make the engine itself more efficient. By doing this, it can develop more power when needed, and also get better mpg.

An RV grind is meant to give more low-end torque, for moving a heavy vehicle off the line.

Also, after thinking about it, with a properly geared transmission (not CVT), you would get maximum acceleration by shifting at, or just past, the horsepower peak, and having the RPMs fall back to the torque peak after the shift.
