just a better platform for pulling.
I think the primary reason is more pulling power per dollar of fuel and maintenance and total cost when amortized over a few million miles. A good portion of truck tractors are company owned; they don't really care about whether the driver is listening to an engine running at high or low RPMs, or whether they have to pump 250 gallons of gasoline or 200 gallons of diesel. They do very much care about the cost per mile to haul the stuff around.
