Tow Bar 2017

[Wombat]

G'Day Campers,

I need a tow bar and probably the electronics. I have a 2017 Caddy Maxi and I believe 2004-2020 will fit.
Is there any other cars these are used on so I can get from a wrecker here in Australia ?

If anyone knows the build code or pics of the factory option that has a plug at the rear or whatnot to make this easier that would be good. I am feeling lucky so maybe I might have it..? ... found some codes and this looks not ttoo lucky but not sure.... 1D0: Without trailer hitch

Even better if someone is in SE QLD Australia can sell me one.

Definitely my second home this Caddy, measured up to fit a queen mattress to fit, 153x204cm will just squeeze in above the wheel arches. lol.

Thank you.
