2008 or newer Toyota Sequoia (with 5.7 and 6 speed) has a 7,400 lb towing capacity (2WD) and 7,100 lb (4WD).
Not quite 10,000 but bulletproof drivetrain.
More bulletproof than a 6.0L/6L90E/14 Bolt? I know people love their Toyotas.....But they cannot compete in this particular segment, HeIl GM & Ford pulled out of the 3/4 ton SUV game.
I would personally avoid an Excursion with the 6.0 diesel.
It's that perception that can make the 6.0L diesel a good buy, I have stated this several times on this forum......The 6.0L PS is, At it's core a really good engine & can be fixed/modified to go toe to toe with any offering at the time.
