My cargo van is a rolling blind spot. I found these spot mirrors some years ago
Automotive Safety Accessories Introducing the New Medium Auxiliary Mirror and thought they would work well for those doing a mirror delete, so I'm sharing
I can see 2+ lanes over to safely change lanes. I run the medium size on each side and figure there 1/4 of a 9" convex spot mirror. Big enough so you can not only tell what your looking at, night or day, but also judge distance and closing rate, unlike those little 2-3 inchers. Short of a 6" or bigger round convex, these are the best spot's I've driven with.
I run mine inverted.
