Just joined this forum and found this thread, I own a 2012 Ram Express RegCab with "Power Nothing" also. I did a lot of research and found a company that makes kits for Power Windows and also Keyless entry kits, the good thing is that the kits are not vehicle specific and can be adapted for different vehicles. (Wanted to help others in my situation that may be contemplating converting to Power Windows and Power Door Locks as this will give you another option to consider).
Power Door Lock Conversion Kit: AutoLoc CA2000 (2 Door Lock Kit with Alarm) bought mine in Jan for $125 (includes shipping) from Amazon.
Power Window Conversion Kit: AutoLoc PW4650 (2Door Universal Curved Windows with 3 illuminated LED switches) bought mine in Jan for $225 (includes shipping) from Summit.
The power windows are very easy to put in, the kit uses screw drives that goes over the factory manual gear. You just have to make sure wherever you mount the screw drive clears the plastic door panels. (Look at You Tube videos, it will give you an idea how to mount).
The power door locks, you will have to extend the wiring harness on the driver's side because it comes up short. (You will need to extend about 1 1/2', takes about 5-10 min).
Note: if you plan on doing the power windows and doors i would suggest on doing it at the same time because of having to run the wiring harness through both doors. For me it was easier running the wiring harness for both at the same time.
If you need any more information on my install feel free to contact me.
Also if anyone has or is considering iPad install let me know of any ideas, currently I am looking at using my 3 front cup holders to hold it. (I am using a bluetooth ODB2 to monitor my engine with the iPad, it works with the iPhone but I need the larger screen because it's easier to see).
