Wow! This truck is impressive. Had a Silverado before. This truck is as smooth ride wise but that is where the comparisons end. This truck is like a giant sports car! (smile) I agree with a comment made in another review. This truck is indeed pure fun. As far as gas mileage. Hey it's a truck! If you are worried about gas mileage get yourself a little jetta. I'll stick with my Tundra thank you :) One word to describe this truck: Power. This truck is what other 1/2 ton trucks want to be when they grow up lol If you're thinking about getting one, go for it.
