I did not have the problem is my Class C or my first Class A because they had a window positioned on that side behind me where I could look out (if I remembered to put the shade up).
On my current class A, I had the same issue and even posted it here.

I solved it by adding another convex mirror to the top of my mirror on that side. If you look up the make of your mirror, you can go online and see if the manufacturer markets an added mirror.
