Gunnado, I have thought about this long and hard
. Looked at the mechanism, cleaned it, re-hitched and unhitched. There is nothing broken on the hitch, or the goose neck
. The only thing I broke was a D shackle on the safety chain. The other chain held very good. Whilst on the way to the top, we drove over some very steep ground, with wash outs, including the Frenchmans Track, across the Pascoe, Wenlock and the OTL, without it coming off again
. I think it comes down to my excitement and not pulling the pin into place when we left Endevour Falls Caravan Park, so user error
.
