Welcome to the site @Cutty3. Yes, I agree the Suburban and the Sequioa are different, however I do know that Chevrolet re-did their seats for 2015 and they're all fold-flat seats that give more legroom and headroom. That being said, they were WAY behind the times on doing this.the suburban and sequoia are different beasts. I had a suburban and just traded in on a used 2014 sequoia. the deal breaker was the second row seat. Suburban's second row would fit a person sized around 5'7 and not above (comfortably). The second row seats in the Sequoia fit ME, and I'm 6'4....and they recline about 3 inches. Yes the motor in the Chevy is more efficient but the motor in the Sequoia is way more powerful with around 400 ft/lbs of torque. We pull a travel trailer and a boat so the pulling power makes a diff. You've probably pulled the trigger by now but just my $.02
