Posted numerous times that would really love the Grand Highlander or TX to be larger and roomier (minimum Chevy Tahoe/GMC Yukon size). Sounds like this is 99.99% not happening.
Hauling 5 plus a lot of gear leaves really nothing in the Toyota/Lexus family. We own a 2016 Sienna Limited AWD and it is insanely loud at freeway speeds, almost like there is speakers pumping the sound of air-whooshing by directly into your ears. And the front seats and front legroom are garbage.
Shoot. Mike, if you're such a BFD, help TMC/Lexus make something to truly compete with the Suburbans, Yukons, etc...
