Well, here's a few things I added:
AAM Finned rear diff cover. Noted by RAM engineers to actually reduce temps by 40 degrees.

Rigid SR2-20" hyper/spectre combo and an aux circuit tapped into the 12V power so I can add a few more accessories

Folding Tonneau, I went with the undercover Flex, but I looked hard at the bakflip and there are more mfr's out there as well like Extang.

Upgraded my bighorn interior to some nice leather seats and also ran full length floor mats since I have benches front and back

Ran an extra long tube for the fuel filter so it doesn't dump fuel all over the front suspension

And also have full-length nerf bars that came with my truck. These are aluminum OEM bars

I also have the Mopar commercial flaps. They're just really heavy rubber.
