This is my first 4runner...although I must admit....I've admired them from afar for many years.
I'm a big guy...so it was a room issue with me, but they made the 5th Gens bigger, and with the Trail Edition, have made some pretty remarkable innovations. Things like a stock rear locker, ATRAC, crawl control, have been nice additions. KDSS is available, but it has to be bundled with the Nav, which is not that nice of feature.
There are a few negitive things, I'm not happy with, like the interior finishes are cheap, and the plastic scratches if you look at it wrong. The springs were pretty spongy, and the nose dive is terrible with hard braking.
If your a mod kind of guy then this is for you. I added a larger battery, a drawer system, made my own steps out of Rocky road sliders, and I'm in the planning stages of a roof rack.
I think you'll like it if you give it test drive. Good luck in your search.
