I mean, it doesnt look the prettiest, and Im not sure how good it is with regards to structural strength and insulation and such, but if you can make it work, and you have an old dead van, its not the worst way to get some use out of something that would otherwise just be junk?
It's got a whole ambiance of its' own, from the inside.
I'm pretty sure that van's table and the booths would make a pretty good spot for beer drinking. You also have ice cold beers just a couple of steps away, in an actual kitchen fridge and not a portable cooler.
Also, in that space one could keep using the car's stereo.
