We purchased our 2021 Vision XL new in December 2020. More hiccups than we expected, but it is a good coach.<br/>We now have a problem with the soft plastic valve plug for the hot water tank. It is a 10 gallon tank. The valve leaks.<br/>Is there a shutoff valve for the hot water. I have looked all over under the rear with none in sight.<br/>Thanks.<br/>Stan Hildebrand <br/>
