Duramax is king of the mountain again

My parents finally traded their '05 Duramax for a new '16 Duramax yesterday. They wanted a two wheel drive truck and after my dad saw the pictures of the hood scoop he didn't like it so they went truck shopping at the local dealer. They test drove a Ram Cummins and the Chevy Duramax and decided on the Chevrolet because of more responsive power, transmission shift quality and just a better ride.
