POSK = Piece of Sh!t Kamado. I'm shocked yours lasted as long as it did. Notorious for shedding tiles and cracking, especially the later ones made in Mexico. Mine was one of the first made in Indonesia, so it held up longer than most.
If that rib technique works for you, go for it. But, you won't need a water pan on a KK. That's one of the things that sets it apart from other kamado style smoker/grills, it's moisture retention. I promise you, it will make the juiciest whole chicken you've ever cooked without any effort at all - no brining, no water pan, and PLEASE, no "beer cans."
