I doubt it'd be legal, cos it certainly ain't legal to have anyone in a caravan when it's moving.
As a trailer it's going to weigh a ton, Mk3's are heavy enough, and they've left the interior in there, making it heavier than a normal trailer.
Shame they didn't do something more interesting with the front, rather than put a plain panel. Perhaps, if they'd made a squashed car, mounted the wings, bonnet and windscreen.
