I think there should be a job like the smuggling one. But instead with goods. If you have bought the Swift(Scania)truck at the cardealer, you should be able to drive to MTL or another building in industrial. He tells you to drive to an NPC placed somewhere (BP or something realistic). The NPC would "give" you some goods in the trailer, and you had to drive them to Industrial or something.
You get the point :b
