You jeep will go anywhere you point it really. It depends how much you want to push it. I never bought into the Rubicon package as I feel the lockers, sway bar disconnects, and lower overall gearing is not an advantage in my neck of the woods. My rig does awesome with the uber high 3.21 gearing in it. It's great on the highway where the higher gearing gives us great gas milage and in 4 low, its' still plenty low to crawl over East coast trails with ease. Also, if you do not plan on rock crawling it, lockers are not needed. I have never needed lockers and I put my jeeps in some difficult places. I put 300,000km on my 2011 I owned, at least 2/3 of that was off road. My 2010 patriot was at 110,000km before I traded it on the 2011 wrangler (patriot was the gateway drug), and I have 2015 patriot as well with 106,000km on it. All rigs have been off roaded regularly and never a need for lockers. Good tires are the first upgrade and you got that conquered.
If I were building your rig it would be tires, mild 1.5-2" lift for some added clearance for trail obstacles, lighting and cargo management and finally money for fuel (both you and the rig). Congratulations on becoming a member!
