All of our last 6 or 7 daily-driver vehicles have had rear wipers (we gravitate toward station wagon/minivan/SUV body styles). I personally find them more trouble than they’re worth: easily damaged, trap dirt and leaves, prevent snow from sliding off, often smear rather than clear, hard/expensive to replace blades on some, and limited field of view. One became such a nuisance I paid to have it removed. I certainly would not pay good money to add one (and twice to add two on split cargo doors). They really need a washer to be much use.
If you do decide to proceed I agree a Ram Promaster dealer is the place to start. They can tell you if it was offered as an option and whether it's possible to retrofit. I also did a quick search on "universal rear window wipers" and found some parts- motors and arms- you might cobble together and build your own if you're so inclined. Anything non-factory will detract from resale value.
I had one of those lenses on a previous van I owned, and I agree they work well, though they will become dirty along with the window and the rest of the back of the van. They address a different problem.
A rear camera that can be activated when moving forward is another option. Yes, it will get dirty, too, but it’s fairly small and quick to clean at each gas/rest stop. A high-mount camera (over the cargo doors) will accumulate less road spray.
For myself, I am best friends with my side mirrors. If an 18-wheeler can navigate safely with only side mirrors, surely I can too.
