I think this van may have just about failed it's MOT if it was in the UK!
Now, in the UK this is a very common sight on the motorways! People (err... I would say almost exclusively men!) taken short on the road, and pissing in 2 litre bottles. If you look on the hard shoulders and central reservations they are strewn with them. This is the first time I saw one here.
I'm not an expert, but I would suggest this pickup is over it's weight limit!
