The Going Cockpit S is an odd name for a caravan. The 'van itself is quite odd too. Dinky, compact, with a pop-up roof and a one-piece GRP body.
It was first manufactured in 2006, fell into manufacturing limbo for a while and is now being imported by Red Lion Caravan Centre in Lancashire.
Here is the listing on their site.
At 750kg and a shade over 4 metres long, it can be towed by just about anything - from a Mini to a government chief whip on a bike. And the groovy, racing-helmet styling doesn't make it look too plebby.
Here is Practical Caravan's jovial video review:
