We are towing right now with our 2014 F-150 and tow mirrors so I took a pic out my passenger window for you.
We have the folding power mirrors and my hubby says they are not enough for lane changes and seeing further back on the trailer. We opted not to get the tow mirrors from Ford as they are huge and create blind spots so we don't want something like that on full-time.
The mirrors we have are the Milenco Aero 2 mirrors. They also make a larger set that look more truck like (called the Grand Aero I think) but my husband finds that these are less obtrusive and give him just what he needs to see without being more blind spot prone.
They stay on very well, don't scratch and fold in with the power mirrors.
