I am reluctantly retired now but drove solo for 33 years long haul mostly then regional and local. I was also a yard switcher for big companies. I am in my early 60's. I used the word reluctantly in my first sentence because as an old school driver for many years it gets in your blood and stays there.

I drove tankers, vans, preferred 53's easier to back and pull, and flatbed' . I drove when there were no cell phones in my earlier years , hauled everything except livestock.
