See if you can guess, from the few design cues in these photos, what this is an interior of: A shipping container? A luxury helicopter? A submarine?
It's a luxury motorhome by German manufacturer Ketterer, and the only two things that give it away is the downward-leading exit on the left of the topmost photo, and the "pop out" chamber housing the couch, which increases the interior airiness--if not the actual square footage--by deploying sideways when this gargantuan vehicle is parked.
Buy one of these and you'll clearly experience what it is to be so rich that it's annoying to others: The Ketterer comes with its own onboard Smart Car.
