I'd recommend looking for this subject in your trailer's owners manual. Mine identifies "deration" may be a requirement only when it comes to the water heater. It doesn't specify a specific altitude, just that "operation of the water heater at high altitudes may require debating." The implication of the need for deration in my manual is that the water heater may function, but will do so in a less efficient manner. "Pilot outage caused by burner lift-off or soothing from a yellow burner may occur, indicating the possibility of carbon monoxide. You may also notice a lack of efficiency in heating the water because of incomplete combustion of the burner at these higher altitudes. Consult with the local propane company, your dealer or the water heater manufacturer for proper derating of the water heater. Change out of the orifice (derating) should be done by the dealer or a qualified service agency."
