Haven't yet gotten around to installing it but I scored a factory Oris hitch off german ebay a while back. Installs like Casey's hitch but looks to me to be considerably more substantial, rated to tow 1900kg. Also has a neat toollessly detachable ball head that when removed leaves no receiver hanging below the bumper. I need to get some eyes welded on for safety chains as those apparently aren't required in the fatherland and probably get the crossbar powder coated. These things turn up fairly regularly & not too expensively, but shipping might be prohibitive; I was fortunate to have been able to get it drop shipped to Berlin whence it hitched a ride in a friend's container to the left coast.
