    Retractable running boards or not?

    We have them (family of 5) and have never once been hit in the shins. You have to back away to open the door anyhow, so I dont understand how you could get hit by them. My 3 year old son who seems to get hurt every fifteen minutes has avoided them. I agree that I (6'1") dont need them, but...

    Downshifting while passing

    Good Day All, I just bought a 2015 Yukon XL Denali with the 8 speed and i love everything about the vehicle except for my payment, and the passing power. I was wondering if that is a problem for everyone with a 8 speed 6.2L? Cruising at 65 MPH, i try to put the gas pedal through the floor...
