Thanks for your time uploading them. Now I clearly see the difference between them. I would need one of those soon... but I`m quite far from your location and as far as I remember they are pretty heavy and bulky too. Are you suggesting me not to choose the factory setup with the fat receiver tube... so it would be easier later to find the ball mount with trailer ball? Or does it come with those? I don`t know about the pros and cons of either one. (In the past I had sedan Volvos only and the hitches used in Europe were different I guess. For example, I never saw a hitch there that had a removable ending/trailer ball but that`s because their rules about having a hitch on the car are different. No rules basically, after you registered the car With a towing device) What`s the price tag on them?
I still have no idea how to ship such a thing.
