The first gen Sequoia is deceivingly large. I tried to get my family ( 4 kids) into a 100 series and they all thought it was too small compared to the old Sequoia. The trouble with the Sequoia is that in stock form it isn't really wheelable. The centre diff only locks with the transmission ( not t-case) in L. The TRAC will get you quite a long way down the trail but when it is time to back out of a situation, you are effectively driving a one wheel drive. There is probably some pin mod to solve this but I haven't come across it yet.
I'm still quite happy with the Sequoia though. 409,000km and counting.
