Does anyone know if the seats are actually different in the AT4 or Denali? I know there may be different/more leather used on the Denali seats, but are the seats themselves actually different? I'm a big guy (6'4", 275lbs) and this is a consideration of mine. I have an order in for a Denali. It still hasn't been picked up. I have a chance to buy an AT4 in the coming weeks, and I'm wondering if the seats in the Denali will be that much better and worth the wait. I don't know how they actually construct the seats and the materials that go into them. I can handle the different placement of the infotainment system, but the seats worry me.
