The easiest solution to this problem is Linehaul fuels the trucks before starting their run. Linehaul will not be on the clock so there is no ticking off dispatcher wondering why the 20 minute window was not met. I can't see why it would be necessary to refuel in the morning, after finishing a run. My run is 500+ per night. I fuel when I get to HST. That tankload will carry me the rest of the route, what the city guy needs, and back to HST with about a quarter of a tank left. Altogether, not quite 575 miles. There is no need for a city guy to refuel the tractor. In theory, if Linehaul fuels the truck then there shouldn't be any congestion at the pumps, in the morning. The next question is, how many city guys use the same truck?
