My "new" daily driver is a '93 Ranger wiht a topper on it.
Unfortunately, the PO painted the inside of the topper windows black, so the only thing my rear view mirror did for me was give me a place to hang my name tag for work...
Spent $100 at amazon, son spent 2 hours fiddling with wires, and I now have a rear view camera and 5" monitor in place of useless mirror. It is meant for reverse, so I have to do something about the LEDs on it (thinking taillight repair tape over 'em to make 'em red). Still hang name tag from it just fine
I've hated the cameras in all of the cars my mom and wife have that have 'em, but without a proper mirror I'm now really appreciative of it....
