Trucks like this are awesome! I never get to see them though, since in California you can only have two trailers. Sometimes if I am going through Oregon I'll see a three trailer truck, and that's pretty neat; but four? I have to see that some day 😃
The more I hear, the more awesome and dangerous the Australian outback seems. I should try and find an interview with one of those drivers. I bet it's crazy driving something that long.
