I've been wheeling my 2012 JKU sport for a couple years now. (my 5th jeep).
I enjoy all trails, but enjoy the trails on a rating sytem of 1-5 (5 being most difficult) I enjoy the 3 and 4 rated trails the most.
I do not have lockers but find that I am able to complete 90% of obstacles and trails with good line selection and good spotting. The guys with the lockers benefit alot from the lockers but as for me, it isn't necessary quite yet. I will save that for when I upgrade axles. No sense in paying for it twice.
3.5" metalcloak springs, Rancho 9000xl's, cut fenders, cut front bumper, custom exhaust, 35"tires.
