I was recently trying to get my 1500 set up for towing before I switched to the 2500. I had chrome mirrors, and didn't want to switch to black plastic either.
Did a lot of researching on the 1A tow mirror replacements, and the OEM tow mirrors.
The 1A mirrors are supposed to have all the fit and finish of factory, at around half the cost. A lot of good reviews on them in multiple forums. 1A mirrors do not have an auto dim feature, but from what I was able to find out, neither do the OEM tow mirrors. (My '14 2500 Laramie Limited tow mirrors don't dim, rear view does though)
I don't need tow mirrors often, so I ended up getting some clip on tow mirrors for just the price of shipping from someone on the forums, then traded in my truck before I ever had a chance to use them. Might not be what you are looking for, but I still have them if you are interested.
Something else to keep in mind. If you do buy a set of flip out mirrors for your truck, you can't just bolt them on and be done. You will either need the dealership to plug into the truck and add them to the computer, or use alfaOBD and do it yourself. (Look up alfaOBD in the DIY thread). The power fold feature is already turned on, and I would guess the turn signals, and puddle lights are as well. I know there is a "Tow Mirror Present" setting in there that is supposed to be on, but not sure what it would actually change. My only guess would be the up, down, left, right adjustments wouldn't quite work right without that setting turned on.
