Truth be told, there is way too much snobbery towards trucking. All You have to do is stick in a set of music or whatever and make sure you are doing your job. It sounds like the ideal job for someone who wants to travel and end up seeing the country and then getting more then enough time off. It would also end up having a good way to fit in plenty of partying.
Nope, you're on the hook for making sure the load is put on there correctly; your hour-plus waits at places like the Oakland Port are on your own time because you're paid by the mile; breakdowns, accidents, and bad traffic are all likewise on your own time; paperwork before during and after; waiting at scales; that's just what comes to mind immediately.
