550 HP. I'm sure that with higher gearing the Kenworth would do better. I think it is disgusting that these little pickups burn so much fuel.

I don't understand how you are coming up with " these little pickups burn so much fuel." ? I'm running combined in the 28-29,000# range and I have never gotten below 8.5 average on a tank of fuel and that is running 70+. It takes so much power to move a load and that amount of power is going to use a curtain amount of fuel.
