This is just your standard 2002 Dodge Quad Cab short bed Cummins Turbo diesel. I have only done a few things to it so far. And that was to help it tow better.
Running a 5" MRBP exhaust
BD exhaust manifold
Edge Juice w/Attitude
Blue Ox gooseneck hitch
And for the little one on long trips a 14" DVD drop down screen.
I just installed Rancho RS9000 shocks and got their new wireless controller too.
