Second Air Conditioner

We have a Cedar Creek CKTS 5th wheel and are planning on putting in the second air conditioner. My question is does the air conditioner fit over the ceiling air vent and we lose that or does it hook up like the one in the living room area?

I don't know, but educated guess: The optional second AC is:

So it discharges cold air into the duct, not directly out into the room as it would if it were mounted in a vent hole.

I'll bet if you go up onto the roof and look close, you'll find the place where the second AC mounts with access to the duct system.

But to be certain, get the install instructions for the second AC and that should answer all your questions. If your RV dealer doesn't have the install instructions and acts dumb about obtaining a copy, then go directly to Customer Service at Forest River (or Penguin?) and I'll bet they'll mail you a copy.

Your bedroom vent goes away, and you'll have some sort of ceiling assembly.
That is, as long as you have 50A service, a breaker for it, it's prewired, and there's a junc. box in the ceiling right next to it.

Jesilas is right, the ceiling assembly depends on which air conditioner you put in, the Dometic from the factory they use the Dometic quick dump. It has a intake with a filter and a vent that you can open to just dump the air in the room or you can close it and the air will blow through the duct system.

2nd AC

Not all 2nd AC's have a vent like that, I have a low profile Penquin and the controls are mounted on the unit. If I had know more I would have installed in after purchase and gotten a unit that used the existing wiring for the thermostat. My wife has trouble turning the knobs because of arthritis in her fingers.
It is vented via the unit itself, the main unit uses the ducts and because it's direct vented it's noisy.

The last Dometic I bought had a dump with controls on it. IMHO, the dump model is more efficient and less restricted than those that use ducts.. .

The second A/C in my Cougar is a drop-in replacement for the usual roof vent assembly. It is the usual "dump" model A/C unit from Dometic as found on thousands of RV's. I, personally, am glad that it doesn't run off the thermostat...the second A/C unit when set on "blast" actually can cool the the entire trailer if it isn't too hot, but, the thermostat is in the middle, between it and the living room, and it would kick the A/C off and on too frequently trying to keep the extreme rear cool. With its own thermostat, at night, we can set the living room unit for cooling the living room and the bedroom unit at a different temperature (with the doors closed). DW likes to sleep in cooler air than "just sitting around" air and I've found the ducts to be less than "efficient" at cooling evenly anyway.

But, yes, at least on the Cougars, the second A/C unit takes the place of the roof vent, but, there is a vent only a few feet away in the bathroom. An upgrade of that fan was simple and it is more than powerful enough to vent the front of the trailer.

Mine is a low profile Penguin, you should check you might be able to change it.

1st Choice

If I were to do it again I would specify this AC for our Bedroom, from what I've read online it's a lot quieter then the Penquin that I currently have and it has Heat Pump available etc. I really didn't look into it when I was negotiating for our FW, I just said a low profile 13.5 AC and that's what I got, but when that puppy is running it is loud!!! Couldn't sleep with it, we always use the main AC at night, bedroom during the day or when we are watching TV at night.

I have a 2011 Jayco Pinnacle REQS? I never ordered the second AC in the bedroom but I sure wish I did as the main AC in the living room barely blows air all the way to the one vent in the bedroom. I pulled out the vent covering and see that it is all wired for the second AC unit so I am considering buying one but they are very expensive. I also thought of installing a fantastic fan in the bedroom to suck out the hot air but they are 12V and my wiring is 110.

Anyone have any low cost suggestions ? Thanks.

What's low cost to you?
I think that about 900-1000 for a second AC and lots of cold air isn't that bad.

True, but I just find it funny that you can buy a cheap house window AC for $99.00 at Walmart.

That's just cause it's a box for 5k btu.
$500 for a box 15k unit.

Coleman Mach 3 Plus is the "standard" 13.5k BTU AC in most RVs. $588 plus freight of about $100.
Link = Coleman Mach 3 Roof Air - 13,500BTU Ducted

About $700 for either Coleman or Dometic 13.5k BTU brands if you pick it up at any Camping World store, but add about $100 if you have to have it delivered.
