is there a difference in the sequoia diff and Tundra (1 Viewer)

I'm thinking or guessing that the Tundra rear axle is designed for payload and hauling heavy trailers and the sequoia is more a grocery getter for mom.
My sequoia ( 2003 ) is pretty weighed down when pulling my travel trailer.
The landcruiser pick up has a full floating rear diff. and am guessing that is so it can be weighed down and haul ass, granted rather slowly but haul.
Is there a difference between the sequoia rear axle and tundra ?

Wasn't the first Generation Sequoia the only one with solid rear axle?

It appears so.
