Just got back in from the Mt Augustus to Paraburdoo stage of the Desert Raid 2013. Had to return home as when the rear suspension bottomed out along the Pigandy Road, the tool box smashed a section of the rear brake caliper off. The brake pipe fitting has taken a big hit too. The tool box has a large dent in the bottom. A whole bunch of us did a group purchase of these things. Obviously not many of us are using our GS's to the full :)
This tool box was supposed to be designed for the GSA by an adventure rider. Not what you would call 'fit-for-purpose'. I now seem to recall Digger mentioning that his tool box broke off the rear brake bleeder.
Again obviously, this could lead to brake failure, not what is desired in remote Western Australia. I will post pictures on my ride report.
