I have an 06 Sequoia. Put 5100s in the front and Dobinsons in the back. Rides like a truck, because it is a truck. I am happy with the performance of both pairs of shocks.
I am not getting at anything that isn't stated in the original post, but you have answered my question about the capability difference- not much, at least in stock form.
Why would the 100 be more capable than a 1st gen, specifically '05-'07 ?
Same engine and transmission (2uz-fe and a750f); both have 2-speed, lockable transfer cases and IFS. Neither has a factory locker for the overlapping years. Clearance in stock form is close.
The Cruiser has more...
2006 SR5 that will go over 216k tomorrow when I drive north to Philly. After catching up a ton of deferred maintenance it drives like new. Saw a wrecked 2005 Limited in the junkyard last weekend with 347k.
