My 19 has been flawless for 65k. If you are going to do any towing, I think 16-18 is the sweet spot. They will have a decent tranny cooler and 16 iirc was the first year the 38 gallon gas tank was available in some models.
As far as problems, the 5.7 liter engine does have occasional issues with the cam tower covers leaking oil, check that closely, view through wheel well area. It is more of an irritant than anything else in most cases.
