I have a heat pump in my Eagle Premier. Just switch the thermostat over to electric heat and the system should take care of the rest with the warm air blowing out of the a/c vents in the ceiling.
If there is a wide difference between the ambient air in the RV and the thermostat setting, my LP powered furnace kicks on at the same time as the heat pump and runs until the ambient temperature matches the thermostat setting. After that, the heat pump runs just as the a/c does, cycling on and off as the thermostat calls for it.
Downside to the heat pump, it's noisy the same as the a/c. Also, if you are cold- weather camping, the heat pump will not warm up your water system and pump or the heated tanks. You must use the LP furnace to do that.
