FWIW, my wife's 2013 Sequoia doesn't have any way to lower/raise the seats manually. And since it has an IRS, you don't lose 5" of head space.

 

I had really thought the 2015 would have had an IRS...

shame.

I have the power flippy/fold seats on my 2009 LTZ... and 6 years later they still work just fine. I don't think you're looking at a high failure rate part.

 

How will Independent Rear Suspension affect towing capacity?

 

capacity or real world?

I've read towing with IRS increases tire wear more than with a solid axle.

But, even if the Tahoe can tow, let's say 10k, I'd wager only 10% or less of people even tow, let alone anywhere near capacity, or often.

So, you can have a comfortable ride 100% of the time, increase rear room, vehicle stability, while giving up 2k in towing capacity, and some tire wear... seems like a win to me.

But... GM says Profits over all, and has given it a body overhaul, but kept the back axle... still a solid axle.

What about this option? Tahoe gets a IRS. Suburban 2500 gets a Solid Axle... best of both worlds.
