Just bought a 2017 Jayco White hawk 29reks travel trailer there is a switch on wall back by fireplace labeled fireplace one way and water heater the other does anybody know what this is? water heater switches are in control panel why is this one labeled water heater also?
As others have said, you can use one or the other. When I took delivery on my White Hawk, the dealer told me I could use the electricity and gas at the same time on the water heater to have continuous hot water. I haven’t seen a need to do that because I usually camp without a sewer hookup and that would quickly fill my black tank.
