Fit of Thule Motion XT Roof Cargo Box with Factory Rack on 2020 Lexus RX450L

Question:

I want to make sure this will fit my 2020 Lexus RX450L. If it fits, will the rear hatch open? We are using this for luggage when traveling long trips. Thank you

The Thule # TH629806 Motion XT cargo is compatible with crossbars that can be adjusted so that they are between 23-5/8 and 36-7/8 inches apart center to center and a front crossbar to the seam where the rear hatch meets the roof distance of 51-1/4 inches or greater.

My research indicates that the factory crossbars on your RX450L are adjustable up to 39 inches apart, and with the front crossbar slid all the way forward, the distance from the center of the crossbar to the roof/hatch seam is 60 inches. If that's indeed the case, the # TH629806 Thule Motion XT cargo box would work perfectly for you. I'd recommend taking a quick measurement just to confirm.
