Bubble Mirrors

 

This little mod cost me $4 total.  I bought these 2" bubble mirrors at AutoZone and installed them on the bottom outer corners of my mirrors.  In this location, I can see my blind spots, which is good when the bed of the truck is stacked high, and I can see my rear tires, which is good for when I am off-road.  The only down side is that they take a little getting used to.
