Towing for the first time with our 2017 GX460 Luxury last weekend, and was using larger clip on mirrors for towing. Never had any issues with them on the GX470, but the GX460 mirrors don't like them. When cruising at 65mph, the mirrors fold in due to the increased drag from the added mirrors. I noticed that even pushing them in with my hands was very easy compared to the GX470.
Stupid thread I know, but I found it interesting that the mirrors are weak tits.
