Thor Wanderer Glide Lite - Furnace/Hot Water Heater q's?

not really familiar with your trailer,, but on ours,, the off/on switch for the water heater is not on the water heater itself.Might look around and see if you can find a switch that you don't know what is for, also not sure which thermostat you have for your furnace, but on ours, the switch is on the side and the temp setting in the slider on the top.
