Tailgate shelter ideas?

A mate has one of these:-

Got me thinking of getting one for the Mk4. Won't be for sleeping in, just sitting in and fishing when the weather gets rough, big enough for a couple of camping chairs would be enough.

2 requirements:

Has to be able to be used on a solid surface (ie tarmac)

Has to be not much wider than the car when erected.

Anyone got any ideas or got one themselves?
