Im looking at purchasing a 2005 CV713 Mack tri axle dump truck. It has a 370hp Mack engine. The transmission is a 6 speed with LL essentially its an 8 speed if you count the 2 Low Low gears. I have never seen one of these transmissions and im curious if any one can advise me on top end speed and Fuel mileage for a truck of this nature....
