[QUOTE=cabmandone;12452183] just go manual extension and call it a day. I've driven my F250 with the mirrors extended all the way out without towing. Make em' like a Ronco... just set em' and forget em.
I also have manual tow mirrors on my dually and they have never been " in "
Once they are set, no need to move them , and a huge field of vision .
Im guessing adding power windows will be somewhat of a project .While, I bet the harnes is there, I would think there will be differences in the fuse block and BCM coding involved .
