I tried several versions. First version was these strap on mirrors from Oreilly's. I actually liked them pretty darn well. Stayed very steady, a bit fussy to install but not too bad. Good vision and such.
K-Force Strap On MirrorsMy dad needed mirrors so we got the CIPA slip ons. I thought they would be easier to put on, but actually took about the same amount of time as my kforce. Neither he nor I liked them. Something about the size, or mirror placement, but they simply weren't as good and easy to use as the kforce.
Later, I got tired of putting on/taking off. Went to a set of factory tow mirrors. If you hang out on f150 forums long enough, you can often find someone wanting to trade a set for your factory mirrors. I bought a set of OEMs for 250, and sold my OEM's for 200. I have $50 in the set. I GUARANTEE they will be the last tow mirror you get for your truck. Visibility both with and without a trailer are superior. They are awesome! Even when not pulling, the visibility they have is remarkable. You can even get them in powerfold if desired. There are some aftermarket versions out there that are half price of OEMs. Do not go to Ford and buy them, as sticker shock will be strong.
Get the OEM style, you'll be glad you did.
