The best advice I have is don't worry too much about it. They're all the same. The important bits that your truck should have is some buttons that make it go, some buttons that make it stop, a round thingie that makes it turn. Hopefully there something for you to sit on. If there is a sleeper, it should have a bed inside it. The rest is fluff. As long as the truck you're issued has the important bits in place, just double check on all the other parts that actually make it go and not crash and use it to make some money.
