Question:
Could you please recommend an easy to install tow kit for a 2021 Lexus RX 350 premium without a factory tow package? Better to stay on a budget. I need everything to be able to tow a Uhaul trailer. Thank you.

Hey Illia, thanks for reaching out!
Here are the parts I recommend installing on your 2021 Lexus RX 350 so you can tow a U-Haul trailer:
- Curt Trailer Hitch Receiver # C73DR
- T-One Vehicle Wiring Harness # 118255
- Mounting Brackets # 18136 and # 18144
- etrailer Adjustable 2-Ball Mount # e66PR
The Curt hitch and Tekonsha wiring harness are the best and most reliable when it comes to standard parts which is why I recommend them. The mounting brackets allow you to store the 4-Way plug right next to your hitch receiver, and then the etrailer ball mount is my favorite because of the adjustability it offers and the quality you get for the price-point.
I'm attaching some installation videos for you to check out. When I looked up your owner's manual online it looks like your vehicle is limited to a 3,500 lb trailer so make sure the U-Haul you pick up won't exceed that once it's loaded up and ready to go.
