My family has always owned chevy's and for the most part never had any troubles with them. none that i can remember any ways. Last year i bought a new z71 with the 5.3. Love my truck, but the fuel mileage isn't the best get about 17 on the hwy and 15 in town. But pulling my 19' nautic star(with everything in it including 49 gallons of gas) to grande isle; it got 14 mpg, which I thought was pretty good.
