Hey Ron, we have the Curt hitch part # C13103 that is a fit for your 2009 Mercedes R320 diesel.
Now do you have any trailer wiring currently? If you have nothing you would need to start with a 4-way which for that we have the # 119250KIT and then convert to a 7-way with the # ETBC7 and then a brake controller like the P3 # 90195 and you'd have everything.

Hey Ron, did you get a chance to set up the trailer wiring with the 4-way and then convert to a 7-way as suggested? I'm asking to see if this setup worked for your Mercedes R320, as it might help others with similar vehicles.
