You can't go wrong if you follow your Owner's Manual's recommendations.

THere is antifreeze, antifreeze, antifreeze and antifreeze.

RV's when we speak of "Pink stuff" We are usually talking about the Potable Water line antifreeze, No best brand, My favorite is compressed air

However you speak of a Duramax Diesel, this suggests ENGINE antifreeze,, and the reply to follow the manufacturer's recommendations is not only the best one, but if the stuff is Pink it's the ONLY one. Now if it was Green we could talk.
