Its pretty good on fuel actually-I have been getting about 19 mpg on the highway and about 16 in town! I can go about 750 miles on a tank too, so it lasts me a while lol!! The V-10 is a total gas hog, but the Diesel is actually pretty damn good-better average than my V-6 Blazer I am selling lol!!
The back up sensors are a god send! I can't imagine why they aren't standard on a beast this big. I have to say after just a day or so of driving I am very comfortable with it. I just have to keep an eye on the signs before entering parking garages lol!
