To answer the question. Yes the small stock mirrors can be put on and the power and defrost will work. I know this as when I bought my '06 it had the small mirrors on and I made them change to the tow mirrors.
Yes, I agree there is a goofy spot the main mirrors dont' pick up and I have just about taken out some compact cars for riding in my blind spot for miles but the convex mirror usualy pics them up, if I remember to look there.
For towing flipping the tow mirrors are better than any mirror extender I used on my last truck. Wouldn't go with any other mirror at this point.
