Hi, My father was a truck driver. He was an owner operator.
That is very interesting.  Was it a difficult job for your father?  It seems to me that the job of a truck driver is difficult.
Traveling long distances by himself, he was often lonely. It's not easy.
How about the loading and unloading aspects.  Was that difficult?  
IT is hard on the body. Also, he had to make sure the truck lived up to all the saftey regulations, so it's a lot of resposibility and psychological stress.
