As an HGV1 holder of 20 years, and a lorry driver in my past life, I can't see where the problems are! Just because you've got 16 forward gears which require a gear stick and two buttons to operate, or a twin splitter where there are only 4 gears but each gear is split in to thirds (low, middle and high).
Oh yes, and it's usually a constant mesh box (ie no synchromesh!) as well.
Actually, reversing an artic is easy. If you want a man's test then reverse a lorry and drag - these have a trailer with a steered front axle so there are two pivot points, not just the one. I challenge any one to reverse those around a corner into a garage on their first attempt!
Now back to the thread....
