What is the average cost per mile for a dump truck?

You need to expense a dump truck at a dollars per hour, as mileage for dump trucking is mostly in a close in area to cities and mostly close to gravel pits, asphalt plants. My own experience is that for every mile you operate a dump truck the cost of operation are double that of road trucks, the wear and tear on them is so much more that the cost of operation is very high, fuel mileage is low due to constant start and stop.
