Thanks for the quick reply! Do you also know do I basically need to buy 3 things: one - the tow bar/hitch, two - the 12N electrical kit (for trailer lights) and three - the white box in photos 32 and 33.

Or does the white box come with the electrical kit? I was planning to get the proper westfalia hitch, but then buy electrics separately from a cheaper retailer. I can post a link to the item here if that's not breaking forum rules?

Thanks again!
