I like it. It would need a screen across the back, but that's easy enough (and likely would be so common/expected that it'd be there after they got through the design-study stage). Design quibbles: It'd be less efficient to tow than the Airstream and fiberglass eggs - nothing sucks like a vacuum.

For the person that asked: The kitchen is opposite the dinette, at the rear.
