I have a 2012 Bounder 35K. 2 air units. the rear air unit is also a heat pump, the front unit seems to be only air. Should both these units be heat pumps? The rear unit will put out heat, it seems...
We have a 2012 Discovery 40G. It has 3 AC units. Only 1 has a heat pump. It seems that the single heat pump works fine to keep the whole coach warm down to about 40 degrees outside. Colder than that and the heat pump doesn't put out very warm air anyhow and we use the furnaces.
