There is a third party company, supposedly working with FMC to sell a user install kit for power folding mirrors, not tow mirrors, to swap out the tow mirrors on the 1500. It will include a new door switch and possibly a wiring harness, and a chip to update the computer to recognize the folding mirrors. But, it will not include the cameras to give you the 360 view.
So, for those of us who didn't read the fine print and got a Ram 1500 Limited truck with manual folding tow mirrors... we gave up the power folding AND the 360 view, just to get wider mirrors and trailer brakes, which could have been added to a truck with the standard power mirrors. There's no option to add the 360 view back to the truck, and we have to go to a third party, for now, to add power folding mirrors... for $1700.
