Stay away from early versions of the 5.3, I think 1999-2003 model years. The engines from those model years suffer from piston slap noise at start up that goes away after about a minute of running. It's not affecting the longevity of the engine (I personally know a 2001 owner with 160k miles and still going strong), but it's annoying.
