What are everyone's opinions on the 6.0 vortec chevy motor? I'm looking at a 2010 3500HD dually with the 6.0 and I want to know if it is going to be ok, or an absolute turd. I don't tow everyday or even weekly, but occassionally I would haul my 10,000# tractor and gooseneck or round bales of hay/cattle. I know mileage would suck and I probably wouldn't be in a hurry, but will the 6.0 do that? If I could justify the extra money I'd get the duramax, but I'm not towing everyday.
