I'm having a hard time figuring out what I can do with the rear seats on my 2019 Laramie with the leather/suede seats. The seats are on tracks and the bottoms easily fold up using the center bottom lever release, but that's the only control I can figure out. Is there any way to make the seat backs lower or recline or to slide the seats on the tracks in any way? I can't find any other levers to control these seats. Also, there are three loop straps on the top back wall behind the seatbacks, but I can't for the life of me figure out what purpose they serve. Any help?
