Default How do I check if I have limited slip diff

I have a 2010 that is approaching 120K and I need to change fluids again. I want to do it myself, but I don't have the original sticker to see if my truck has a limited slip diff. What is the easiest way to check, VIN or code on the rear diff itself. The Haynes mentions that limited slip rear axles need to add a Mopar additive.
My VIN is 1D7RV1GP9AS105438

One nice thing is that with almost 80K of my miles driving it has been 16.5 mpg with lots of driving on logging roads in 4x4.
