Not much of a back story. I bought it brand new with a COSTCO/ GM offer which at the time seemed like a winner. It's just a $69k bad deal, horrible ride. I've had a better ride in an old Army deuce and a half. I'm certain it would be quite costly to make it ride like my old 2004 Silverado 4x4. If GM can't do better, I'll switch to a Tundra, or Ford, or RAM.
