Hi Chris,
thanks for your compliments.
The top will be removable, so I must not meet any rule or law because it is just cargo.
The skin will overlap the upper rivet line of the utility part.
The utility trailer has got a title and official approval inside german laws.
I do not need insurance and I can pull it only with a not sealed license plate with the numbers of my motocycles plate.
The skin is not aluminum but 0.6 mm (1⁄32 in) stainless steel and windows are added after finishing the skin.
Tom
