It always surprises me when I read the Tundra threads and the gas mileage gets reported. I have a 5.7, 6 speed, 4x4, double cab, Tundra that does not have the tow package. It gets 20 mpg driving regular. If I'm towing or hauling something it drops noticeably, but 20's a pretty fair bet for normal highway driving. Is it the lack of a towing package that's helping it?
