BEST 'ERGO' ?

CF, how can you say that the 3VTG cab would have been more successful than the Marathon when you know absolutely nothing about it ,all you know is what you`ve seen on here a few photos of a prototype that looked like a yank mounted on an AEC chassis for testing.You dont know what the ride was like ,the space inside, the visibility ,you know absolutely nothing whatsoever ,like most of your postings on here its either hindsight with your usual quote of history shows ,or just disagreement for the sake of it .I still cant quite make out why you compare the Marathon with the much higher powered F12 when it was the F10 which had a very similar output,maybe you wouldnt like the results of a test match between those 2.
