I am hoping someone out there may be able to assist me. I bought this new coach and this is my first camping trip and when I turn on the furnace on the Winnebago control and set it for 79 degrees, the max it heats to is 72 overnight. This morning it did heat to the set mark but over the night times these past 3 days the same ocurred. The propane is on as the hot water heater works seamlessly, there are no obstructions in the vents. Thanks in advance.
