Your first problem is you are trying to put the Mack motor in a class with Cummings or Cat. They are not the same. The Mack is a high-torque rise engine. It will pull in a much broarder RPM band. This allows for the use of a 5 speed trans where others need 9+ gears.
Now if you are looking for a road truck Mack is not the best choice. But if you are looking for something that will take a beating and still keep on pulling Mack may be the truck for you. They are made to go off the concrete and stand up to the work. While they will not preform like a true off road truck (Cat) they are the best choice for off and on road use.
If it were me I would be looking for one with a 237 and 6 speed. The 6 speed is better than the 5 speed when it comes to off road.
