they try to have at lelast one new piece of equipment on each...pull?
either a new cab and old trailer, or old cab and new trailer....
or old cab, one old overnight pup, and one UPS freight pup...etc.
If you're asking a question, the answer is NO! If you are stating, what you consider to be facts, the answer is still NO!
Sorry, but nobody on the local freight side or the parcel side for that matter, is smart enough to fill the primary spots with matching, mixed or painted equipment going the same direction, headed for the same destination or other spots, pulled by the same driver or handed off to a relay driver.
You get what you have in the lot. If you're a small terminal and equipment is short, you don't have the luxory of just picking out matching equipment to send with the nicest driver or to make the best PR statement.
Hell, I'll bet most of the Motor Cargo trailers still have expired license plates! True or false? It was true just a few months ago.
Same with parcel side. You pull what shifters put in the door to load. Sometimes someone upstairs sees a ratty trailer sitting MT out in the yard and wants to get rid of it. "Mr. Brainiac" tells the shifter to put that in door XX headed for XXXXXXX, we'll get rid of it and never see it again. Mission accomplished. Three days later, guess what's heading in our gate?
No, maybe on paper there is a plan, but in the real world, it ain't hapnin!
