I'll watch this later, heading out soon. That is the idea I am after. Mirrors on our arto stick out like the K.........charlies ears, often I have to be very careful when driving down a narrow street EG, North Berwick High St, I don't knock someone out with a mirror. Entering and exiting my rear garden is tight, same at our France landing pad, 25thou either side clearance!!
More important is, gauging how tight to have the actual mirrors on the arms that attach to van, too tight, no give if mirror gets a whack, it is a fine balance, too loose, mirror moves due road conditions, which affects rear vision.
Thanks for replies to date
