Do I need tow mirrors for the '03 Expy? I had a pair for the 99 that were molded to fit those mirrors, but the new ones are bigger and Square. Without hooking it up and taking it out with the trailer it think it would be hard to judge.

Thanks.

 

I often wish I had larger mirrors that would extend but I make do. Position 3 of the memory is for my settings with the addition of the mirrors slightly silted down so I can more easily see the trailer wheels.

Last I knew no one was making an add-on mirror for the ones like on my 2000 with the turn signal so I would guess no one is making them yet for the '03's.

 

I just traded my '02 F150 for the '03 Expedition and the mirrors seem twice as large. I'm not kidding, they are huge on the '03! I pull a 20ft boat with mine, so I don't need anything extra, but I don't see why you would need the add ons with the new mirrors.
