City traffic, a van and often a trailer means no mirror deletes for me. So why not add a mirror Kammback?
These are sold on e-Bay as rain visors. For $5 I got two pairs shipped (thinking about doing the top and bottom).
I was presently surprised that they make such a nice streamlined shape. As a bonus, the mirrors will stay dry in the rain. The mount with VHB tape, I haven't actually mounted them as I want to see how well they sit on my other cars.
