Lyn,
I bought a brand new 2014 crew cab LTZ 4x4 6.0vvt in February, and it pulled like it had 200hp. RUN AWAY from the new 6.0 trucks. Before you buy, hook up your trailer and run it down the highway.
If you are pulling an enclosed trailer, it will not even be able to run in overdrive at 65mph on flat roads if you have a headwind without pushing it hard.
I tried premium fuel, e85, and had no luck.
With 4000 miles, I towed my 8000lb 24' enclosed from Omaha to Eddyville and got 7.04 mpg from Omaha to Des Moines while trying to run 70mph.
On the hills, the tach was pegged at 4400rpm trying to keep it at 65-70.
I traded down for a 2012 2500hd Duramax and havent looked back.

I got just under 11mpg running 75mph from Omaha to Denver for the ET Finals and the truck never downshifted.

In town/part highway empty, the 6.0 mpg was less than 11.5mpg. Duramax gets almost 18mpg on the highway empty.
