As for the towbar, you won't find anything as there is nothing to find.
Officially it is not recommended, the same as the first gen however there are none being made for the new gen.
Although they are quite capable of towing your small box trailers without much problem, its not suitable for a car trailer with car.
So this is one of the reasons no one is prepared to make one cause they could be liable if something happened to the vehicle.
I have seen them fitted but it was a tow bar for a V6 and had been botched to make it work.
