New Viral Clip from Toyota

I haven't posted a viral clip for quite some time now, but here is great new one from Toyota (via Volker Weber):
It got a lot of things that can make viral clips successful: it looks like an authentic home video at first, not like an ad. It's really funny and it has an inventive underlying idea with a great surprise effect at the end... All powerful incentives to get people to send it around...

Unfortunately, I don't know very much about it. It comes from Adcritc.com and not from Toyota itself. The clip is also not featured on the official Tacoma website.

Does anyone know, if it was or will be part of a bigger campaign ?
