If I were to speculate about the reason for this, it would be to compensate for the RX-L weighting 242 pounds more than the standard length RX and to keep the combined maximum weight of the vehicle with passengers and luggage and a 3,500 pound trailer under the 9,360 pound maximum shown in the RX owners manual. If this is the case, it would not be the first time that Toyota has reduced the potential number of passengers to reduce the total vehicle + trailer weight.

This begs the question: Do you really need the long version of the RX? If you are going to leave the 3rd row stowed most of the time like you said and since the 3rd row isn't suitable for adults larger than dwarfs (no offense meant to dwarfs), then maybe the regular RX (with the Tow Prep Package) would be a better fit for you.

I was about to get RX350, then I felt I needed to get L instead, plus I was able to find deal similar in price for L.
But with everything said in this thread, I think maybe I should go back to regular RX350 as you suggested. Thank you.

The 20’s have less sidewall than the standard 18”; adds some firmness to the handling in and out of corners. If towing is important to you, more important than 4.3” of length, then go regular RX. Now if we were talking trucks, and the choice was between 5.5 ft vs 6.5 ft, I’d say go 6.5 ft. Happy car shopping ��.

I did not see any mention of tire sizes until your post. Both lengths come with both sizes and so it can't be assumed that the tires caused the difference in stability.
