Had a couple like that yesterday, god that wind was fierce!!
My van is really dangerous because the massive back doors are like sails and the stays that hold them open are so weak, even a little puff of wind and they swing shut. Plus I've got them fully lined with 9mm ply and loads of tools and hose ramp mounted on them
It got me once, I reckon I was only a little bit away from it breaking my leg. Any weather, rain, fog, snow, don't mind working in it but i HATE the wind!!
