I have never seen it before or any of the other threads.
I did a search for 6x6 after I posted this (sorry, wrong order) and found several ebay links to dead auctions but no pics of this truck. I also found some references to perhaps placing this in the "Land Rovers That Suck" category. That was my first thought too. Of all the things I have considered doing to my truck I have to say that this has never even crossed my mind.
In the end I thought I would be kind and give Berry a bump to help him sell his truck.
