Be sure to check the USB charging station if it has one. Ours did not work as well as several others on this forum had problems also. Have them test the San T Flush system for you ours leaked inside the coach. Have someone inside when they apply water to make sure it's not leaking inside the RV. Many others had this issue too. Make sure all the outlets work. One of our 12 volt on the dash was not even hooked up.
