I didn't even know power folding mirrors were available for Rams, however it looks like they're an OEM option
on 2013 Rams. (scroll down to the spec sheet right after the colour page)
I'm not sure if what you're looking for exactly is available in the aftermarket...
The first step I'd take, (and it would cost nothing to check) is inquire with your dealer on the cost of ordering the OEM mirrors. Be prepared to be shocked
but at least that'll give you a starting point for reference. Also check with the service dept and see if the 2013 mirrors could be swapped onto your truck - if it's plug & play that would make things MUCH easier.
Also do an internet search internet search
for aftermarket options.
