We have an outdoor kitchen, its the main reason we bought the trailer. Its the center of our activity when at the campsite. We never had a problem leaking at the kitchen. The living room slide is a whole different animal. The sink drains into our grey. We have everything set up out there. The coffee maker stays in the outside kitchen and readily available. We have only cooked on the stove inside once, and that was at a rest stop at the Bonneville Salt Flats due to a storm outside.
