We have a single heat pump and I wish that we had gotten both AC units equipped that way. It works great until the temps get down to about 40 degrees. At that point it rapidly loses ability to heat the trailer. Closer to freezing (32) it gets far weaker. It seems to be able to heat the trailer to almost 30 degrees above outside temperature so at 40 outside it struggles to make the trailer get to 70. Cycle times will also decrease and it will go into anti ice mode to clear the outside ice build up on the coils. The pump will run as of in AC mode and the fan will shut off as it heats the outside coils to get rid of accumulated ice.

If you are on a meter for electricity in the park it's economy will depend on temperature and the cost of propane locally. On a non metered space it is WAY cheaper than propane as long as it doesn't get down below 42 or so.
