2019 KPTS had the dealer install a stackable. Cold water wash only, wife uses it all the time. Shakes the whole rv while in the spin mode. The dealer put one hold down clamp front center that was a joke. I later added two clamps on each side in front, helps a lot on spin shake. But so far it’s still working & shaking & vibrating the rv with cold water wash only.
