I think the caravan is a Cheltenham of around the late 70s, possibly a puku? The car is a Rolls Royce, probably a 1920s 20/20. We have a Royale club member who occasionally uses his to tow his Touranger.The 'van in the background is a Safari, again late 1970s.Can't work out who the people are, but I'd bet they're members of one of the Rolls Royce clubs!
