Outstanding effort by all!
FedEx, and others sending out doubles in the winter, put the driver in a terrible position.
In my youth, I was ran an division of a manufacturing operation and had the shipping and traffic departments under my purview among others. I had a traffic manager junior to me and we had about 13 tractors, 20-24 drivers and about 18 trailers as I recall. We avoided even running our trucks “bobtail” in any condition due to stability issues on wet roads or snowy roads.
As we used flatbed trailers for hauling steel components the issue of doubles was never there but we felt that drivers needed to be able to maximize their hauls and income without a dispatcher putting them in a box. We tracked dispatch times to allow arrival for unloading based upon the distance.
