My brother ended up learning to be a truck driver when he became unemployed for a while. He got his HIAB and an ADR rating and worked for an agency, some jobs he liked and some he really didn't but, a job was a job, anyway, one day he came to my works in his truck and let me sit in the drivers seat. It was they type where the cab appeared to be floating above the rest of the chassis, and I said it was like driving a double decker from the top deck... it might've been a Renault Magnum?
