Just bought my first Toyota. A 2010 Tundra Crewmax 5.7L. Could of gotten by with the 4.6L but was told by dealers its not offered here in the Northeast. Does anyone know if it is true?? Prety sure I will like the 5.7L. I am only 10 mmiles to work so its not like the mileage will be a huge deal. What are you seeing for mmileage with this truck configuration?
