I drive lgv's for a living so used to towing, had caravans for 35yrs and know how to load etc.
Scared the crap out of my wife.
Still no idea what coursed it.

That sounds horrifying, but at least there's only scuffed paint and no injuries. Presumably it's a setup you're used to and was previously predictable? I just wonder if it was some sort of malfunction such as caravan brake sticking or tyre going flat?
