Something else that hasn't been addressed but maybe should be, is that all models of the 4Runner have Vehicle Stability Control (VSC), which computer controls your brakes and throttle input in extreme maneuver situations. You almost can't get in too much trouble with that. I know I can sail off onto a highway off/on ramp in my 2" lifted basic non-KDSS Trail faster than 90% of the traffic I have to contend with is willing to. I have also seen a 10-13 Trail that had to have KDSS go sailing around a curve running 5 - 10 mph faster than I was comfortable doing so and showing absolutely zero body roll. I was mightily impressed at that little feat because I am happiest bending a curve, even in this thing.
All that being said, if you want the Pro because of its looks, that is fine. If you want it for its handling of potholes, that is fine also. They're all going to feel a little squishy and have some nosedive compared to what you have been driving. It's the nature of the beast. None of these quirks has ever made me feel I was on the edge of control at any time in mine so far, and some of them have actually grown on me.
In hindsight, if I were to change anything, it would have been to at least test drive a KDSS equipped model. Less for its better on road handling than for its perceived improved ability to flex off road. But I will admit I was ignorant that KDSS even existed at the time I bought mine, I knew what the differences were between the 3 main models, but not the smaller detail differences like KDSS and X-reas. Going on one year later I still think I would prefer the Trail Edition either with or without KDSS over the TRD Pro. NOT because I don't like the Pro. I think it is a sharp looking ride. But because I don't like to buy "Packages". I have made the upgrades that I WANTED over the past year to get it where I want it, and I am still under what I would have paid for that package if it had been available.
I'm not hating on Pro owners. I am reinforcing that you should continue to do your research and make an informed choice. I still get drawn in by the "shiny" on occasion, but I'm getting better. Heck, it was that shiny new nose that sucked me in in the first place!
