There is zero chance they’re shipping sub-assemblies for some random African shop to weld together, unless they’re selling to an established auto manufacturer (which is not what this article is implying). The entire point of selling a chassis is that the manufacturer has done the hard work of assembling it and making sure it meets quality and safety standards, so that downstream customers can modify it without spending hundreds of millions on crash tests.

You can clearly see from the driver cab that this is a cab chassis meant to provide the minimum required safety for a single occupant. This is a structure welded together by robots in Toyota factories with decades of tuning and process improvements, not something welded by a third hand Lincoln tombstone. The only “innovative” feature I can see is that it’s a chassis tailored to meet safety standards in Africa for a lower cost, rather than California or the EU where that cab would never be allowed on the road.

(I stopped reading when the author pivoted to their housing pet issue so I may have missed some details, but none of the quotes from Toyota imply anything but a standard rolling chassis to me)
