I've read on other forums that the GX being lighter and having more aftermarket suspension options is better for high speed offroad. And city use. The LX being bigger and possibly more capacity being better for "overlanding" or whatever it's called now.

How's the Sequoia with 4.7L compare? Same engine. Same tranny and t-case? Just bigger, and lower quality interior? I'd imagine less acoustic material for sound mitigation, thinner glass, and different ride. But the ability to haul more gear is appealing. And they are dirt cheap compared to either Lexus.
