I've heard they were thirsty. I did look at buying a V8 auto 100 series and getting it converted to a ute, but I have heard there is a chance that GM will bring Chevy trucks to Australia post the end of Holden/Commodore/Calais in 2017. So I reckon I might wait in hope for some good news along those lines. They'll probably do something stupid like only sell them in Diesel in 2500HD and only petrol in 1500 spec.
