We have an 07 Escalade ESV and make 6 or 7 long trips a year between houses. All Interstate. We are in the car about 13 hours and my wife and I both find the seats are uncomfortable and the ride somewhat harsh as we have the optional 22 in wheels. Does anyone have (or had) an Escalade and an MDX? If so how does the long trip comfort compare? I love the A/C seats in FL, so probably would want an advance. I also assume the ride in an advance is better with the handling set for comfort mode.
