Not exactly on topic perhaps but maybe this is related info.
I stumbled across this video a few years ago and have been using this mirror set up since. I will admit, when backing into parking spots my 03 SLT with tow mirrors and included mini convex mirrors, made this blind spot mirror set up easy to adjust to and maintain. By that I mean I was not needing to "re-adjust the mirrors" for a given situation. My 03 did not include a rearview camera.
My new 2018 RAM Sport with the Sport mirrors (read: not tow mirrors,..so they are smaller and did not include the mini convex mirror) is not so much the case,...but I do have the rearview camera option which helps, and I've added the convex mirrors by Wadestar which fills that void on the drivers side nicely. To keep things symmetrical I've also got a Wadestar unit on the passenger side, but it is less useful as compared to the driver side (as others had commented). So..here's the video about how you might like to set up your stock mirrors. As the video dude states "it takes some getting use to", but once your schooled up you might be saying "I'd wish I known this years ago."
I wonder,..has anybody already set there mirrors up like this?
FWIW,
