Question about my Jeep Compass

I just bought this 2017 Jeep Compass High Altitude. I have had it for 2 weeks and as I said in my introduction post, I have always had full size Chevy 4X4 pick up's. I did have a 2003 Trailblazer for a short time. I loved it but traded it to my youngest son so I could get my truck back.
My questions are a couple. What is the difference between the High Altitude and Latitude packages and I finally read a yellow sticker on my door jam that says my Compass has a Rough Country suspension. Is this common? I noticed it does ride a bit rough but not anything I would complain about. I need to look under it and see what I can find. My brother asked if maybe it has a 2 inch lift. I honestly told him I have no idea because this is the first Compass I have ever been in and am not sure how high they are. I do know the more I drive it the more I like it. Anyone have any ideas?
