Want one...

Have you seen this?

 It's a 21st century Winnebago, basically.  You can go camping in it...so long as you're not doing off-road in uneven terrain.  Hell, you can live in it, if you want, it's the fold-out kind of set-up.

These diagrams show you how it works, and the bed is over the driver's seat.  Plus it's electric and runs off the sun; there are solar panels on the roof.  Talk about a tiny carbon footprint.  Me want.

Of course, I could just win the lottery and buy a little Renault Kangaroo Mini, fix that up to be a sleeper in the back and toodle all over Europe in it, like a modern day hippie.  No apartment needed, just a drop box for mail that I'd have to go to every so often.  I'm sure I'd get sick of it after a while...but then again, you never know; I may be a gypsy at heart.
