Welcome to the forum and congratulations on buying a Jeep! You'll quickly learn that JEEP means "Just Empty Every Pocket". LOL!
My suggestion is to take it on a few trails, and find out what it needs to do what you want it to do
. Some people mod theirs to crawl the malls, some to do dune running, some for mud, some for rock crawling (me). Each has different needed mods.
Use the search function and look at the sticky threads at the top of this section of the forum to get some idea of what works and does not work. Join a 4x4 club or Jeep club...that will expedite the learning curve. But most importantly, enjoy your Jeep!
