I Built a -- ONE MAN -- MICRO Camper

You can travel, get a good nights sleep, great for the trips away for a few days here and there without expensive hotels etc. and it's a lot better than sleeping in the car - unless the car has fold down seats and you can put your feet into the boot etc...

I used to tow a trailer behind a bicycle and on the open plains, issues such as wheel diameter, and aerodynamics REALLY become important because you have SO little power to overcome rolling resistance and wind resistance.... This was a very important series of lessons in power consuption and aerodynamics and wheels and suspension etc.. This guys trailer is good, but it's not brilliant. He thinks being light weight, lowers fuel consuption - and to a point it does, but aerodynamic shaping accounts for 90% of the drag in this design..
