I also don't understand why Chrysler located the latch anchors in between the left and center positions of the 3rd row. It's an awkward place. I would not use that position unless you really need to use the latch anchors for quick installation and removal of the car seat. Instead, I use seat belt installation with the car seat in the left seat.
I was planning to use a seatbelt installation for two harnessed boosters in the far back as well. The latch positioning is very strange. The headrests and the seat belt buckles make it seem like a very challenging place to get a good installation.
