This vehicle was a replacement for a 2005 2500HD Duramax SLE and the engines are nothing alike. The new Duramax and six speed Allison is quieter, smoother and the towing power is incredible. We are towing a 35 foot travel trailer and it is like there's nothing behind you. The Z71 package does increase the stiffness but the ride is excellent. The interior rivals my '07 Denali. If you gotta tow, this is the one to buy.
Incredible power, excellent transmission cooling, integrated brake controller, outstanding fit and finish.
Center console storage, overhead storage, side airbags, stability control, standard running boards, power sliding rear window with a defroster.
