Hey thanks for replying. I actually purchased a 2016 Sequoia and there is a ton more interior space. I have the 42 x 21W x 30H and a 36 x 25W x 28H and there is plenty of room to spare. Both 2nd row seats are up with more leg room than the Tahoe/Yukon. 5" extra space on the sides of the crates. A carpeted 2 x 4 under the back of the crates levels them off, and the Sequoia suspension can be lowered a couple of inches making it easier for my 11 1/2 year old twins to jump in. Plus, the rear window retracts into the tailgate - the dogs love that! I've been a GM person all my life, but the Sequoia if more "large" dog friendly than the current Tahoe/Yukon.
