Wayne, before you buy the slip on mirrors, look at this
http://www.tow-n-see.com I have about the same set up as you will. I left the Mckiesh mirrors in the garage on the last trip. They are just a tad small, but can be adjusted with the electric mirrors. Also with a wider truck like yours, they work find. I got the convex one for the curb side, but wish I hadn't.
