Driving a Quad 4 trailer, 150' 0r 53 5m Roadtrain

Lots of people, especially overseas friends, love Aussie roadtrains and they're always asking what it's actually like to drive one, so I've put together this clip to show people what happens. This is a Mack prime mover, with a Cummins engine and 18sp Mack gearbox. The roadtrain has four trailers (a Quad) and is 150' long (53.5 metres). Empty, it weighs, 65 tonne and laoded, 150 tonne. It's speed-limited to 90km/h.
