Found this on the Trailer Owners facebook page, and couldn't let it go. 650 ks later, it is home.
2005 Shadow, with a poly block swivel hitch. No brakes though, but it tows well empty, and only cost me 0.1km per litre, which I think I can forgive. Did include the inverter for the solar, and a tiny MC battery to go with it. That shall become some sort of small deep cycle one in due time.
Now all I need is a rack on the lid for an extra swag. Maybe.
