All those funny trucks we see in the Indian vids - the ones that don't seem to have a cab - I wonder were they originally comventional trucks with "normal" petrol or diesel engines, cabs, windscreens etc; and did all those things succumb to neglect, rust etc so that by the time they need a Changfa repower they are down to a husk - like an old Nissan Patrol in the outback, where the body has long disappeared but the chassis, running gear and a seat or two remain? Or did they start off life as a shell? They seem to have a conventional looking bell-housing with maybe some support bearing on the input shaft and a few belts-and-pulleys . . .
