One man band that serviced several end of line terminals, I had more duties then a l/h shop mechanic and often worked with vendors across a couple terminals to get repairs and PM's done, I mostly did all the PMs and repairs I could fit in.
At one point in the 80's through the 90's I did 3 terminals and as some cleaned up would move to another terminal, at that time the Terminal manager was my boss so if it had something to do with a truck it turned into my job.
At different points over the 38 years I was there I had 3 different convention fleets with with a overdue Pm rate of less then 1% only because I was better at tracking the trailers and finding them then Dispatch was..............................
I in serviced new tractors to the P&D fleet and de-processed sale units, over the years I even did L/H to P&D conversions
