4.8L V8 engine reliability
I have a 1998 Sierra with the 350 engine, and considering buying a little newer truck, 2000 Sierra 4X4 with the 4.8L engine. Several people tell me that the 2000 4X4 will get as good as, or better gas mileage than my 98 2X4 model. However, I know nothing about the trucks since the change over in 1999, and I am concerned about the reliability of the smaller 4.8L engine and tranny. I don't pull much, but I stack the miles on, which is why I buy older used trucks. the 98 Sierra is just now broke-in with 160,000 miles on it, but I think the newer truck drives a little better, and may get better mileage, plus the 4x4 which I would like to have, but really don't need. Can I expect 200,000 miles from this 2000 model truck with no major repairs, as I have gotten from my older GMC's. Your experience and thoughts appreciated.
