Sarah,
An Air Conditioner is an "air source heat pump" that runs in only one
direction. The only difference between an A/C and what most folks know
as a heat pump is a set of valves that reverses the coolant flow through
the evaporator and condensor coils, reversing their function. That is,
they now cool the outside air, "pumping" the heat INto the trailer.
Hunter has one in her A/S.
