Sorry I couldn't resist. Hope you find the source of the odor.
Wouldn't be the first time I missed that boat
I stayed up for a couple of hours while DW tried to sleep wondering if we were ever to awaken again. I explained about CO alarms and smoke detectors but standing watch was going to have to be the solution. About 04:30 I gave in - everything was working as it should and the coach was warm.
I checked again this morning in the light, and all was normal. The best I can figure is that something happened in the Aqua Hot that burned and created the odor - maybe an impurity in the fuel - obstructed the flow of fuel and stopped the burner. The odor would have had to come through the floor of the coach from the Aqua Hot bay. But there were no warning lights of any kind on the monitoring equipment. It will bear watching though - maybe it will happen in the day when things are so much more clear
Wouldn't be without one though -
