I mainly run the back roads. A lot of what we have around here isn't horrible as my rig in stock form could handle it. I lifted it with the OME springs and Bilstein shocks to get it leveled out, be able to handle the extra weight of my gear without changing the handling capabilities too much, better ride quality in general, and to clear a little larger tire without worrying about tearing things up. If I get better tires, it would perform as I'd like and be able to handle most of what I want to run. I think my desire for sliders comes from just easier access to the roof is all. Side steps would suffice but they're usually flimsy and fall apart.
I have no desire to build this into a rock crawler as it's also my daily driver. I'm sort of building a Swiss Army knife or Leatherman multi-tool. She may not handle amazing in all conditions, but I could make it through. I haven't found a need for more lift or much more armor. Mainly just wanting that extra reassurance and the step mainly. With that said, with say a TRD Pro T4R, I wouldn't really need to do much in the way of add-ons since it's plenty capable from the factory. The WJ unfortunately wasn't built from the factory like that. The Overland edition of the WJ came close.
