I like it now that I have a Duramax 2500HD crew cab. I did an acceleration test and my queen mattress slid off the bunk. It is a pleasure to tow with this truck. Towing with a Tahoe meant jouncing and bump steering and high revving and just general fatigue at the end of the trip. The Duramax just does everything right- it goes where I point it, it is stable, lots of power without drama, and the whole family is comfortable. Truck is still comfortable empty, too. Plus, exhaust brake! I tow all over the Pacific NW, and not having to be on my brakes all the time really is good. At 76k my truck's OEM brake pads are still barely worn.
