Agreed, I've never had to scope mine out but I find they're much nicer for backing up, especially around corners. They're also much nicer just for driving, as the convexes eliminate most of your blind spot. They're a bit pricey but worth it IMO, and don't have to worry about the poor quality that often plagues aftermarket brands. Only other thing is, the running lights do not work. I haven't found a ton of info on it but as far as I can tell, you need to change out the door harnesses for them to work, or wire them yourself. The signal lights work though.

 

We moved about a hundred round bales yesterday from the field to storage between mine and my father's '99 F-150.
