Camping setups

I'm curious to see what other Versa owners have figured out for camping in their cars.
Anybody found any good quality mattresses that form fit the inside of the car?
How about roof mounted batwing awnings that clear over the top of the opened hatchback?
How about car tents that fit the opened hatchback well?
And anything else!

Show us what ingenuity or convenience you've whipped up!
