Looking for opinons of how well a Heat pump works in cool and hot weather vs the standared A/C and gas heater.

We have the heat pumps on our (2) Coleman A/C's and have been very pleased with their operation. Generaly heat pumps are good down to approximately 35-40 degrees then the LP furnace will kick in. Also, if you initially set the inside thermostat 5 or more degrees higher than the inside temp of the rig, the LP furnace will also come on until both the stat setting and the rigs inside temp are within usually 4 degrees or less. I'm sure others will chime in with additional info.

We have two heat pumps and they do work well down to 40 degrees, saves a lot of propane. As far as the cooling part goes they do that well too. No more than they cost extra, it's the only way to go.

Ditto Bob's comments -- he convinced me to replace our A/C with the heat-pump option. We will never own another RV without a heat-pump; however we only have one, compared to Bob's "two"!

We have 2 of the newer heat pumps that work efficiently down to around 33 degrees. They work really well, considerably quieter than running furnace and a lot less costly. HVAC system will automatically transfer from heat pumps to furnace operation if outside air temp do not allow heat pumps to keep inside temperature at desired level. AC's run equally well, would not have a RV without the heat pump option.

On Excels with the two stage furnace, the heat pump will not auto transfer over to the gas. I don't know why, that makes a difference, but ours came with three separate thermostats.

We have heat pumps in both of our roof air conditioners and we wouldn't be without them.
As others have said, they work well down to 35-40 degrees, although they do not warm things up as fast as the propane furnace. Some systems will run both the heat pump and furnace if the temperature differential is great enough, but ours does not. The other down side to the heat pump is that the warm air comes out the ceiling AC vents and tends to stay up near the ceiling, which means your feet may get cold. That said, they are still very worthwhile and will save a lot of LP in cool temperatures.

Had roof mounted A/C on my 94 coach and have basement heat pump on my 03 coach. Love the heat pump as it is MUCH quieter and I don't get the drainage, and stains, from the roof units. Used it in 121 degree temps in AZ last year, and in 20 degree temps in VA this year.
Love the heat pump.

Our heat pumps do a good job down to 40 degrees. I just a soon use the electricity that I paid for in parking fees as burn my propane. Under 40 degrees switching to propane is a must unless you like cold air blowing out the vents.

There is another positive feature about the heat pumps I forgot about. At least on our Allegro Bay, the standard ACs are 13,500 BTUs while the upgraded ACs with heat pumps have a cooling capacity of 15,000 BTUs. For a price difference of only about $700 we not only got the heat pump option, but also increased cooling capacity. The increased cooling is helpful on very hot days with no shade.

We have the heat pump/AC option in our 33RSE. (I just cked the build list.) But the FAN blows from the ceiling in the LR/KITCH area. LOUD FAN. If it wasn't cheaper to use the park heat than the propane furnace, we wouldn't use because of the FAN 
Does PI mount some in the basement and others in the ceiling??
