Chevy Bodies style nicknames?

First its government mandate to meet their mileage requirements across the company. On a side note,why is wrong to want better mileage from a truck? If you could drive your truck and get 25mpg instead of 8 without sacrificing performance why would you want to waste the money? If my truck could get 35mpg like my dd instead of 8-10, Id drive it the 80 miles a day to and from work.

Fair point, I suppose I meant the things that sacrifice performance.
