I've been lurking around for awhile. I traded my 2016 JK and a 02' Ford truck for a Mojave. I have 3000 mi on it now and (knock on wood) no problems.
I got the Mopar mirrors from Allmoparparts they are great at interstate speeds, Rugged ridge door sills, screen protector, and I am pretty happy...
The Arc hangers are great and even without the hinge steps the center is more toward the mirror.
I hang mine in the window track.
I had a JK that I hung the doors on bike hooks and never had a problem with the seals
