Great thread! Just read the whole thing and got super excited about the 2013 sequoia Platnium we just bought for my wife. Ours has a ride height adjustment control in the cab and a suspension softness control as well? Have not done any reading on these or played with them yet, anyone out there have info on these gadgets.
Love the way your sequoia looks and performs! What size rims did you get? Ours has 20" on there stock and I am looking to put some good AT tires on and may want to change the rims.
Here is ours (hers lol)

Rock-Eater. Thanks. The Sequoia has worked well for me. The main limitations are, 1. not a world wide distributed vehicle (limited aftermarket support), 2. Independent front and rear suspension. There were a couple of times where more articulation would have resulted in more grip and less drama. That said, the beast of an engine and low gearing really come in handy.
The platinum comes with air bags in the rear suspension. If you lift the front, you will be limited on how much you can lift it in the rear with the height sensor. I've seen people raise the platinum around 1.3" by just sliding the sensor down the adjustment arm. Generally anything more than that you will run into rear shock top out issues (which you can read about in this thread, hence the custom rear shocks). You can also ditch the airbags and get a standard coil setup if you prefer that. Just depends on how much work you want to do.
As for the tires, I went to 18" rims to get more sidewall. The largest tire you can fit in the spare wheel well is about 34" max. My Toyo MT 275/70/18's are 33.6" when new per Toyo's website. I wanted to make sure I could fit a full size spare of the same tire in the spare well.
Toyo makes an Open Country AT II "Extreme" in a 295/60/20 @ 33.9" and 295/55/20 @ 32.8". Both should fit without rubbing issues but you may want to try one first. Be sure to get the "Extreme" version which are the E rated tires. That is if you plan on doing any off-roading. Good luck. Let me know if you have any questions.
