This trailer has been built as a hobby trailer to carry go-carts and motorbikes, etc. It has a rear opening door and adjustable tie points in the floor. It is built from insulated fibreglass panel, Duragalv frame and quality running gear. A problem that is had by most other enclosed trailers is that they can drip condensation when it is cold and overheat in the summer, the insulated panel in this one won't have those issues.
