As I started as a Mechanic thought hard about skipping the HE, was back breaking usually filthy and outdoors where no elements protection save what you carried, set up many tarp shops.
Got a gig with FELD Truck Rental in STL back in the day. Clean, dry most of the time, nice newer rental fleet. Worked in the shop at 7th and Russell for almost a year got promoted to second shift foreman due to a retirement. Stayed there a couple years was feeling the itch to move along and the owner asked if a few of us could work on a company wide Fleet Control road call breakdown system. Sounded as a challenge so took it. Mentally draining, 24/7 office open hours where we had done it on a call in basis for the local district before went to full company coverage. Did NOT give up the extra money work where the odd hours did lend to working a second then additional jobs,
End of three years burnt out, moved back to shops, company was taken over by GELCO Corp, I was already working side jobs with my own shop in St. Peters MO. Was starting to take its toll, too many hours too little sleep, beat up breaking down physically. Now I reap the benefits of those years, tired, sore all the time, still have some stored crap in my head pops out when needed. Moving to the Nuke was not so much the better but retirement pension, insurance, other plusses while still afforded time to work other stuff.
