I too have a W/D, my wife wouldn’t have it any other way. Our unit was plumbed for it from factory but I did the purchase and install myself. After much research we went with the stackable; heard too many bad things on the combos but the again opinions are like As……. Never mind, you get it. Some love the combo.
I actually did a YouTube video on my install you can check it out @retiredandrollin on YouTube. It’s pretty detailed and most like it except for one guy that said I speak too much; he’s probably right.
