Hey Jack,
The difference between the K-Source # KS3990 and K-Source # KS3891-2 is the first one has dual lenses while the second one has single lenses. I've messed with both of these and the dual lenses are definitely better because you get to adjust both of them individually. This maximizes your viewing angles so you have a safer towing experience.
I actually got the opportunity to test fit these on a 2019 Audi Q7 so I'm attaching that video to this page for your reference.
