No, I really have trailer 579107 in my mirror

So I get to the Pilot in East St Louis, Illinois this morning and swap (heavily) loaded trailers with my trucking counterpart. We exchange paperwork and make some small talk then head off to the scales then back to the open road.

As part of this process we also use our satellite units to indicate we've made a switch and we each enter information from the paperwork so the system knows we've got the right paperwork for the right trailer. Only, my dispatcher is sure I have trailer 589860 on board and a simple glance at either of my side mirrors confirms that I have trailer 579107 in tow behind me. Paradox, again.

I send off a message telling him I'm sure that is the trailer behind me and go about my business. Four hours later I arrive in Rochelle, Illinois where I drop said trailer at the consignee and by this time my dispatcher has gone home. Soon after I punch in the proper codes into the system the weekend dispatcher sends a message asking what happened to trailer 589860.

I almost didn't respond but eventually I typed out another message and even phoned in to make sure they were reading it left-to-right instead of the reverse. My simple question: "Is there no way to ask the system what truck currently has trailer 589860 hooked up to it?"

"Nope."

My lord.

Then I'm told that the system says there are three trailers at this consignee that have been there for a week without any further updates. Having just left said consignee bobtail because there are no empty trailers I think our trailer tracking system is full of poo poo.
