Last year we took our first long trip, from IL to AZ. It was winter, but just above freezing at night, so most of the in-between CGs we stayed at were being used by people staying one night and moving on, like we were. I was amazed how many people hooked up their water and sewer for one night. Then had to fight with unhooking and putting it away the next morning in cold and near darkness. And sometimes rain! It seemed crazy to me. You've got several days worth of fresh and sewer water storage, it's no big deal to use them for a day or two. Be brave!
