Stop trying to be reasonable or make sense.If I could have one I would...It has bad flex because by design 6x6's don't allow for a lot of wheel travel. Prop shaft from one rear axle to the other is why. Pinz is independent all around and is as bad if not worse than this Benz for flex. The Volvo 6x6 is only slightly better than a Pinz and it is on leaf springs. So even a $500,000 Benz 6x6 is going to be limited with rear axle flex simply due to the nature of the 6x6 design. I would imagine though that a design similar to the Pinz but with long travel stuff, ie trophy truck style, would net the best flex on a 6x6 since the diff doesn't move up & down like on solid axle trucks. The main limiting factors with any 6x6 is the rear prop shaft between rear diffs. That and the turning radius is usually very poor. But traction wise, they drive up anything.
