The two Dometic units I've looked at are the Brisk Air 2-15,000 BTU and the Penguin 2-13,500 BTU.

The price of the Brisk Air 2 is substantially less than the Penguin 2. Why?

Are they both "plug and play", with regard to the existing control wiring in my Excella?

Is one unit quieter running than the other?

I had a house in TN with a heat pump. The heat was wimpy, not as good as a regular furnace and needed wood stove backup on the really cold nights; as was the AC not really AC that was serious about cooling in the hottest days of summer.
Are the RV units similar wimpy, or is the AC comparable to an AC only unit that just happens to also make heat?

Any heat pump, regardless of brand, type, or size, looses its heating efficiency as outside air temperatures drop, the exception being those that draw heat from the earth or ground water. When outside air drops really low those that have the condensate coil that use outside air are pretty much useless. The heat pump at my house is installed so that a natural gas furnace comes at ~30+ degrees F.

Will there be any modification or additions to the existing thermostat wires, the one with jacks, if I use an AC only unit? Will the CCC-II will control the furnace using these existing wiring to the thermostat?

I really do not understand the bundle of wiring that is in the ceiling of the trailer at the roof unit. I have not studied those wires at all, though I have a basic understanding. I know there is a 12v supply. I know there are two wires from the furnace. Will you clarify/give me more detail of what the other wires are for, and I will have to do something to these wires if I install the AC only unit? Will I just remove the connector and re-wire the new unit using the same wires or will there be some that will not be used?

Will there be any modification or additions to the existing thermostat wires, the one with jacks, if I use an AC only unit? Will the CCC-II will control the furnace using these existing wiring to the thermostat? IIRC, There are about 6 wires that come to the Airstream wire bundle from the A/C unit; those being a 12VDC positive and ground, the 2 furnace wires and 2 yellow wires that are for load shed devices which are not used in Airstream trailers. There will be 4 coming from the Airstream: 12VDC positive and negative and the 2 blue furnace wires. You will also have 2 RJ-11 phone cables from the A/C unit that terminate in plastic unions. These are for the comm. cable that runs to the t/stat (CCC-I or CCC-II). You can use either one. All of the wires from the Airstream should be connected to the mating wires that lead to the A?C relay board. These wires are identical in all Dometic units that use the CCC series of t/stats.

I really do not understand the bundle of wiring that is in the ceiling of the trailer at the roof unit. I have not studied those wires at all, though I have a basic understanding.

Will I just remove the connector and re-wire the new unit using the same wires or will there be some that will not be used?
Again, all Dometic units that use the CCC series of t/stats have the same wiring plan. It is a wire-for-wire replacement, and you simply plug in the RJ-11 into the new union from the new A/C unit.

"The two Dometic units I've looked at are the Brisk Air 2-15,000 BTU and the Penguin 2-13,500 BTU.

"

The Brisk Air II is a high profile unit with a smaller roof footprint. It is less expensive because the condenser is vertical instead of horizontal and the fans have more room for placement. The coils are also higher. I have been told that all of these characteristics are less expensive to manufacture. They are not made for use with the aux. drain kit, but you can modify one if you are handy. I have been told that these run much quieter than the Penguin II, but have no direct experience with specific decibel levels of either unit.

Either will work with your existing t/stat but require a retro fit control board. The new units that are ordered for remote t/stat use are designed for the CCC-II, which is a plug and play install with what you now have. They can also be ordered for the single zone t/stat, which will require 18AWG cable for the t/stat connection.

Understood ...
and the AC is less efficient as well.
But for an RV heat pump I was curious about the AC being a real AC, capable of making cold, or still just a pump.

Lewster, Thanks again!!!! That really helps.
I'm finally getting the meaning of the acronym/names for the various parts.

On the Airstreams built in the last 5 years, the non ducted systems, which AC or heat pump units were installed at the factory? Are they still using the old plastic drain pans beneath the unit or have they changed to the auxiliary drain kit?

I'm on my third Airstream and this current one is the only one that has had a heat pump instead of an air conditioner.
I LOVE the heat pump because we camp in cooler weather sometimes and it is nice to be able to heat with a campground's electricity instead of our propane.

Also, the heat strip in the A/C is not on a thermostat, such that you either manually turn it on and off. You can't leave it on or you'll get too hot, so on a really cold night you don't have the ability to set the temperature and forget it.

I would rather use a portable electric heater, mainly because the noise the heat pump makes when the compressor cycles keeps me awake at night.

I believe that Airstream did away with their proprietary plastic drain pan about 4 years ago and FINALLY went with Dometic's auxiliary drain kit.

CAVEAT!!!!!!

They STILL don't install the drain kit according to Dometic instructions!!!!

There are to be 2 sealing gaskets used on a Penguin when the drain kit is in place. This allows for proper compression of the gaskets (50% of original height, which is 1" compressed) for specified sealing to the roof.

Airstream has been using only 1 gasket and using a binding sealant beneath the gasket to be sure that they won't leak. They definitely travel to their own drummer and against the tide of 10's of thousands of properly installed A/C units with interior drain lines on just about every other RV company's products.

I have noticed that protrusions from fasteners and bolt heads at the bottom of the A/C chassis pan are resting directly on the roof, since a single gasket will not allow for proper gasket compression when the drain kit catch cups are in place.

WHY NOT DO IT RIGHT THE FIRST TIME.....AIRSTREAM??????

Atwood a/c

A few members have stated that the Atwood A/C systems work really well and are notably quieter than anything Dometic puts out.

I spend a lot of time in Virginia Beach, and much of that near NAS Oceana - the sound of freedom comes from the jets doing touch-and-go practice carrier landings at the base.... so I don't get too exercised over the noticably noisy A/C heat pumps, but hey if there is something better for the folks who don't have the much vaunted ducted air, well it pays to learn.

Comment on that Lewster?

Thank you, Paula

I'll take a stab (as a novice) at explaining why I choose to re-install a Dometic product.

The existing control wiring from the wall thermostat to rooftop unit is similar to a phone jack for the Dometic units. If I would use a different brand rooftop unit I would have to add to or modify that existing wire, which could require digging into the walls and ceiling.

Also, the furnace is now controlled by the same wall mounted thermostat as the rooftop unit. If a different brand is used, it might require an additional/separate thermostat, requiring more digging into the walls.
