Vince (or other), please let me know if you added a hitch to your 2021 RX350L, including wiring?
And whether you purchased OEM from Lexus, or went third-party (Curt, etrailer, etc.)?
We recently purchased a 2022 RX350L off the lot, and it did not include the towing package (and thus no hitch), but does include the rear door kick sensor. I've heard/read that we'd need to relocate the kick sensor (via an accessory package) or lose it's capability (no big deal to us now).
I'm also having trouble finding any third-party hitches that are confirmed to fit the 2022. I feel 99% sure that if the hitch fits the 2019+ RX350L that it will also fit our 2022, since nothing I've read would indicate any such change for this generation of the 350L's.
Also, has anyone installed (or considered) the 'stealthhitches' option for their RX? I like the idea & design, although their site also does include an product for the 350L 😞 I may email them to inquire.
