2007 silverado 4x4 CC, 3.73 gears and 4.8L motor/ 16-18 mpg in town 19-22 mpg intersate/freeway. Plenty of tow power & room. I do not know what the 5.3 gets MPG wise. I was going to buy the Tundra, smaller, more expensive, worse MPG overall. Same with the Ford 5.7L ...worse mpg & 15K more. The silverado road nicer than the other 2 IMO & costwise a lot less. Not a single problem in the 5 yrs I have owned it.
