I will have some geniune VW trailer hitches available in the spring (about
6-8 weeks, I hope).  These are the actual hitches sold by Volkswagen South
Africa for the Vanagon, although I am getting them directly from the O.E.
supplier to Volkswagen.  The hitch actually has Vanagon bumper brackets
integrated into it.  You simply remove your bumper brackets and bolt this
hitch directly to the bumper bracket holes in your frame.  The bumper (metal
or plastic) bolts right to the brackets, just like the stock ones, except
now you also have a hitch.  So it's a simple and sturdy installation.
Still, these are light duty hitches, intended for small utility trailers and
the like.  Will come with 1-7/8" and 2" balls (not a receiver hitch).  Price
will be very reasonable, should be well under $150.
