The only difference between an Ergo cab and a 60s yank tank is the height of the cab relative to the chassis, a comparable day cab yank has, as saviem says, a pitiful BBC measurement, so much so that half of today’s drivers wouldn’t fit through the doorAs usual Carryfast, bless him, is away in his little fantasy world.
All of the above makes perfect sense to me and, no doubt, everyone else who reads it.
Those KW and Peterbilt cabs were effectively coachbuilt jobs, using aluminium instead of wood, aloominum being cheap in America. If you look at the Paccar website, they are boasting about their latest innovation- presswork. Yes, the new range of KW trucks has a pressed and welded cab (some of it, at least. I bet there are rivets and a bit of fibreglass somewhere on it), just like an LAD or an Ergo. Why did the US market prefer such a crude method of construction for so long? Even with the availability of properly-engineered cabs on Macks, they still held the KW in higher regard.
There’s just the inconvenient issue of both the New Zealand and Australian markets in addition to the US one to add to that.The fact is they can’t all have been wrong and in general natural selection won’t allow any truck manufacturer to survive who’s products don’t make the grade.Blelieve it or not Jaguar Cars actually went from pressed steel welded monocoque construction to bodyshells made up of bonded and rivettet aluminium panels as part of it’s modernisation programme taking it into the 21st century.
