98 would be the best year imho but 97-99 should be fine, in 98 is has a chance of being equiped with the 5.9L not all 98's but some, easy way to tell just by looking is if the hood has vents inline with the headlights, if you get a v8 might as well get the biggest. My friend just picked up a 5.2 even though... lets just say if it's got 35's on stock differentials, a leak on every gasket the vehicle has, and spark plug wires that wobble at the plugs and feel like gummy worms in certain spots from either being sprayed with degreaser or the like or some how obsorbing oil, stay away from it. You pretty much come with the essential tools for purchasing a vehicle, eyes and ears, if you see problems or potential problems chances are they're problems and if you hear anything out of the ordinary, and don't know what it could be, you probably don't want to know what it will cost to fix. Look and listen high and low. Thats my best advice, aside from that don't settle and look for the features that matter most to you.
