RE: C's RULE !!!!!!!!!!
At FedEx I was told that a run is offered first to the size unit it SHOULD be on, no matter who got there first.
In otherwords, if it's a B load, it is offered to every B first, then C's, then D's, and lastly E's, etc.
Therefore, using that logic, if most of a companies loads are "C" loads, a C Unit will stay busier than a D.
That's the point of having different size units. If I'm sitting there in a van, and they offer my van load to a D unit, just because he's been there longer, I almost guarantee the next load will require a D Unit!!!
I don't know about other companies, but I have talked to some C Unit drivers with FedEx, and they "seem" to be busier than most D unit drivers I talk to.
A "C Unit" will definately get dispatched around a "D Unit" if it is a "C Load" so as to keep that bigger truck availible for a bigger load.
