Chevy 6.0 Super Ike Gauntlet

The GM 6.0 is a great dependable engine that has been in production for quite some time. My FIL has a 2011 Chevy 2500 with the 6.0 and pulls about 9000 lbs travel trailer with it. Fuel mileage stinks, but he has never had a single issue with it. For the cost savings over diesel, he is okay with a little slower drive on steeper grades.

I'm not a GM guy, but I wouldn't hesitate for a second to drive a 6.0.
