Paul Elkins is a designer, a dreamer, and inventor. He's been sketching up new ideas of unusual inventions ever since he was a kid. As an adult, he still hasn't lost his imagination, and now has the ability to actually take some of his dreams and turn them into reality.
One of his ideas was a bicycle pulled "travel trailer," if you will, he designed for use at the Burning Man event in Nevada. While not actually designed for "road use" it's obviously "pullable." That's not Paul on the bike, incidentally.
Paul's little trailer is set up with electricity, a small fresh water supply, even a built-in food dehydrator. The whole rig scales in at about 100 pounds, dry. The bed converts to a lounge for daytime use.
Paul has some other interesting designs and innovations on his blog.
