Camp in the City

If you’re in a crowded city with a minimal budget (say, in the finals of a World Cup or something) and you don’t mind just camping it out, here’s an interesting solution of a tent masquerading as a covered vehicle. Blend into the urban landscape while surreptitiously having a good (and cheap!) night’s sleep right in the middle of the city!
Where can these be bought from?
Hey gatekiller,
Sorry – I have no idea where (or whether) you can buy this. Saw this on a couple of sites but it seemed like nobody has any original source.
