Best way to answer your questions would be to go the RAM and Ford site's and build a truck. That way you'll know what options are available in the trim level you are interested in.
I will tell you from my recent experience that it's hard to impossible to find a truck outfitted for towing that had the specific equipment I wanted. Most of the trucks I looked at on the lots were eitehr really loaded up with a lot of extra costly stuff or were bare bones "contractor/landscaper" white work trucks. I ended up doing a factory order to get just what I wanted.
