Towing mirrors for 03 F150 4x4 crew cab
 

All the ads I find say that their mirror won't fit crewcab model. Not sure why. Does anyone know where to get some. I don't want the slip over existing mirror set up. I'd like power adjust with telescoping out kind to be more specific. Thanks for anyone's help. I've been on Amazon already and they all say won't work on crew cab model!
