So what's the verdict?

Overall, I flat-out love the engine.

But let's first address the big issue: You can tow 9,300 pounds with this configuration, which is well down from the nearly 13,500 pounds that the mightiest gas-powered V8 Silverado offers.

That still isn't bad, though. The ultra torque-y Duramax feels abundantly powerful, doing a passable imitation of a much larger motor while presenting an appealing option for customers who want to pay less at the pump and don't need to haul houseboats.

I suspect the motor plus the Z71 pack would make for some exceptional off-roading thrills, but as with all trucks of this type, the best I can do test wise is to drive around in rain or snow and sometimes venture into muddy, unimproved parking lots.

The upshot here is that while I still prefer the Ram and the F-150, this diesel Silverado is my favorite number there. I were buying a Silverado, this would be my choice.
