Is your Chevy one with the motor extension mirrors? I had a truck like that. I just added a concave (or canvex??) mirror out on the edge to see the side of me better.
I think you can maybe purchase these to replace other mirrors but may be expensive. The original mirrors weren't quite long enough to see perfectly behind but could tilt them in a little to see along side the trailer and use the concave ones to see beside me.
