The factory Toyota/Lexus hitch is the least visible one available. Plus, it is designed to fit perfectly and the electrical connections are simple. Getting to the electrical connection is not so simple since it requires removal of the luggage area.
Hopefully, the RX is equipped with a tow package.

GDixon,
Thank you for the complete post on the RX350 trailer hitch back in 2007.
I have a 2007 RX350 FWD and would like to install the Toyota trailer hitch. Is it absolutely necessary to make the electrical connection if I'm only using the hitch just to transport a bike rack? From your post, it seems that is the most difficult part of the install, and I would prefer to skip that part if I can.
I also noticed your RX350 is an AWD. Is there any difference in the install for a FWD?
Thanks again for your very helpful 2007 post, and thank you in advance for your response.
Daniel
