I really wanted to see what you did here "
C piller with screws and home made standoff's made from plastic spacers. I cut away the stock mounting from the inside of the interior panel."
I have a 2023, since new, 44k miles on it and i have had zero issues, still have the original battery and tires. I bought and carry a portable battery jumper but I have only used it on my Wife's avalon.
