"I do not feel most people
"I do not feel most people buy a full-size truck for the gas efficiency."
As an original owner of a 2006 Tundra, I have literally been waiting for Toyota to come out with a more efficient Tundra. The fuel efficiency does not need to go from worst in class to best in class; it just needs to be significantly improved. I am anticipating a 22-23 MPG number while retaining Toyota dependability. Performance of 25 MPG or better would be a game changer.
