More importantly, it looks like one of those older episodes where it was just three guys having a bit of a lark and somehow ending up on television. Like when they did the $10,000 supercars, or the $1,500 Porches.
It looks like Clarkson behind the wheel in the image where it is being towed. My first thought was that it would probably be a May idea. Either way, it looks fantastic, caravan designers take note!
