I once worked on a tomato farm in Australia - without a doubt the most back-breaking work I've ever done - but after a few days they offered me the chance to become the driver instead, which is to say, the guy who tractors a trailer out to where the pickers leave their filled bins, hoiks them onto the trailer, then hauls them back to the shed. I never quite got the hang of reversing the articulated arrangement (you have to turn the steering wheel 'the wrong way' at first, to get the trailer reversing in the right direction', then ease it back at the right time and pace), but I got away with it for a couple of days till one time I lost concentration as I reversed into the shed. There was an ominous thud, the roof sagged just slightly, and that was me back on the picking again.
