I didn't review all (any) 77 pages.
Here's a dislike. I travel with my cargo van & the dislike is the sun visors. They are short and there is a void between the two.
Since you are moving the drivers one from front to side the fix should be the passenger side. It needs a slide piece that will slide to the middle to cover the difference. I will work on something even if its just temporary.
Can I get an AMEN? lol
I LOVE the Transit sun visors. Primarily for the depth of coverage. I've never had a vehicle where the visors came down so far. The "stowed" position in my van is flipped all the way forward, rather than against the shelf. But, 99% of the time, my driver visor is mostly down.
I have not noticed a problem with the gap between visors. My passenger visor is stowed forward, so, I don't expect it to do much, anyway. In the mornings, I do sometimes find there's a crack along the pillar, where sun is shining through. The solution may seem odd, but, it is to angle the visor toward me -- thus, being nearer to me, blocks the side. You might try that position for your center gap.
