Thank you for the feedback, guys!
Yeah I don't get why you'd set the camera to show THAT much of the tailgate. Obviously (if the camera can't be adjusted and has been at this angle the whole time) it didn't bother me during the test drive or the first couple months I owned it but, oddly, now...
Anyone know how I can double check the camera alignment on my '15 Tacoma? I swear for the first couple months I couldn't see that much white on the bottom. Seems like the camera has shifted down but now I'm second guessing myself. Maybe it actually has been at this angle the entire time.
