So being a new RV it has an "excess flow valve" as part of the propane regulator assembly. Its part of the POL connection between the tank and the regulator, a check valve in the POL connection. Anyway, I took the POL from my turkey fryer propane burner and exchanged it with the one on the RV.
Voila, the furnace doesn't go out after firing for two minutes, it actually heats up the RV. Not only that, the water heater works on propane now and I can have them both going at the same time.
Now I understand the concept of the excess flow valve, it limits the flow of the propane in case of a leak. However, how does the inanimate object tell the difference between the stove being used and the increased flow required to fire up the furnace at the same time? Let alone if the water heater needs to fire up also?
So, yes, I removed a "safety" device. A safety device that was not working. It was preventing my furnace from working properly. It would engage when the only thing occurring was the furnace heating up the RV. The same with the water heater. I guess the safety device decided that the hot water and warmth from the furnace was bad for me.
