I met the couple that own(ed)? This truck when they were driving through San Antonio, TX. I believe his name was Carlo Kapp. I've seen this truck in person and I can say its very nice. It's a V8. Couldn't tell you if it participated in G4 but I know that they drove around the world. They also mentioned that they were almost finished with their journey and wanted to sell the truck here in the states instead of importing back to the UK where they lived. He gave me his email as I offered to get him some information on selling it but my wallet was stolen that same night in the hotel I met them in. It is a very cool truck and they were very friendly people. I don't if they sold it and this guy is trying to re-sell it or what but I figured I'd chime in.
