I use Velvac mirrors, these are bolt-on installation and they generally come on cutaway cabs, such as Class C motorhomes or box trucks. They are heated, powered and have turn signals, and I got them from ebay.
The downside is that they don't extend/retract, so I fold the arm and rotate the mirror when not towing. Otherwise I am too wide and it makes me uncomfortable in traffic.
