All of these heaters really three wear items. The motor, (brushes, bearings) the burner and the heat exchanger. The heat exchangers life is determined by duty cycle and the failure is usually burn through. This is why these installations should always be used with carbon monoxide and propane sensors. Operating them for short cycles will reduce the heat exchanger the same wy running your engine for short trips will rot out the exhaust. If the RV is of a real size it is probably better to use an standard RV heater as they are priced better and available in a wider range of sizes. 35,000 to 40,000 btu/hr is common. Part s are more readily available.
