My ultimate plans for my 23 footer are a clean roof ala Ken Henderson's
beautiful example -
http://www.gmcmhphotos.com/photos/our-x-birchaven/p437.html

I have been planning on a low-profile air conditioner as Ken had used, but I
see now that the Penguin II is about the only low-pro model available
(9.5"). With the recent great news from Larry, Bdub, Jon and others about
the Atwood Air Command A/C units, I am kind of on the fence. I like the low
sleek look of a low-pro unit on a slick 23 footer, but I also obviously want
lots of cold air pumping from a (relatively) quiet unit. The minimal price
difference between the units either way isn't relevant to me.

I'm hoping that someone here has some direct experience with both of these
units who can give me their opinion or recollections about output, noise,
etc. For instance, I know that the Atwood has two motors, but I think the
Penguin II has only one. Would that make it noisier or just not as
efficient?

I appreciate all opinions. Thanks,

I had fully intended to put a Penquin low profile in the front hole, but
Jim B told me that the last couple he had installed sounded like hay
thrashers. That cinched my decision on the Atwood.

Guy,

Thanks for the praise of "Tweety Bird" -- even if he is showing is age
(every corner bears some evidence of my carelessness). :-)

I mounted the low-profile unit just because of the looks. I don't know
that there was a better choice in '98, but I suspect there is now. The
Penguin is noisy and runs all the time. And it certainly does not have
excess capacity for our Dixie summers -- it's all it can do to keep up when
it's 95*F & in the sun. If I had to replace it, I'd be looking for a 15k
btu unit -- but not a heat pump.

Ken H.

Hi Guy

If your going for looks, the low profile would be the way to go. Especially on the 23'er. But if your going for practicality your going to want the Atwood. It gets hot in Sac, but nothing like out here in Texas. I'm running A SINGLE Atwood on my 26'er that doesn't even have a working dash air unit and it's totally comfortable thought the cabin. Driving or camping. Food for thought, Atwood might be a year out from a low profile unit. Scott

I bought the atwood primarily because it was the lowest amp model for the btu's. it also happens to be one of the more inexpensive one's, and money played a huge role for my decision. I still do not see how you can beat the engergy usage for the BTU's.

I did not care about the roofline, because I still have one other big ugly A/C, and a ugly roof pod,and an ugly rain cover on my front fantastic fan.

coleman low profile one is the mach 8. never heard one run. it uses 2 motors as well, but is rated more amps then the atwood by quite a bit. I think the coleman seems to be a superior unit then the dometic penguin ii in my research.

the penguin ii, I think does not have a low profile in a 15.5k, but comes in a 13.5 k. it uses one motor. the dometic 13.5 uses about the same amps to run as the atwood 15.5

if you look at the different manufactures roof line, I would say the atwood is the ugliest. even some of the other one's that are not low profile(dometic, and advent), the outside shroud is a little better looking then they ever have been.

the dometic 13.5k unit I just had installed in a trailer at work, was the cheaper model they make, has what in my opinion is an ugly cheap inside unit, and cheapo knobs.

my atwood, I do like the look of the inside unit, even though the roof is kinda ugly.

They're all crap. Carrier was the only one worth buying, and even it is noisy.
Consider a Mini split with the condensing unit mounted on the rear above the bumper.

I chose the Atwood because of the way they handle the air flow. From what I read it looked like the most air flow of the ones available. It’s big and not too pretty. I liked the idea of the digital pad, but now I’m not thrilled with it, a door with knobs would be just as nice, no better, no worse.

I like it. I’ve never had the chance to use the heat side of the thing for any reason but suspect it will be nice to have. It blows lots of cold air.

Thanks to everyone who responded. Again, what a great group of GMC lovers!

Based on everything that I have learned to this point, the Dometic Penguin
II is OUT of the running and the Coleman Mach 8 low profile unit is IN in
its place.

The Atwood model is gaining many points, but frankly the outside unit is the
only thing holding me back. I hope they do introduce a low profile version
within a year. Unfortunately I can't wait that long.

I'll change the question to the group but leave the subject line alone. Does
anyone have any direct experience with the Coleman Mach 8 Low Profile vs the
Atwood Air Command A/C's? I'm interested in output, noise, service, gripes,
etc.

Thank you all again,

Chris,

I heard of this mini-split on the net about a year ago. Was it you that
brought it up? I haven't seen that anyone has installed one in a GMC yet. Or
have they? Any pics?

Ken,

"Orion" continually aspires to look and function just half as well as
"Tweety Bird" does! She is a great inspiration for us.

Seriously, since our brief meeting at Applied last year where I was able to
see some of her features, I have been studying the photos that you've posted
just to gain some ideas of things I would like to incorporate into my GMC.
In fact I peruse your folder often -
http://www.gmcmhphotos.com/photos/u40-kenhenders.html

The Penguin is out for me, but besides the Atwood I am now eying the Coleman
Mach 8 low profile 15k btu unit. I have a hunch that the Atwood unit will
provide more cold air though, and at lowers amps, and possibly quieter. The
plot thickens...

There is nowhere to hide the condensing unit. Maybe if you removed the propane tank you could work it in, but on the bumper seems unattractive to me.

How about "in" the bumper? As in - spacers to push the bumper out, then the
condenser between the body and bumper?

I don't follow the argument against the heat pump, except perhaps cost. Mine is a great asset fall and spring. I'm following this closely, I need a second (rear) unit, which needn't be a heat pump. The 13,500 Dometic heat pump is marginal here in the august sunshine at one show I attend regularly. I've a fantastic fan in the rear whose hole should accommodate any of the units being discussed.

this spring, there was two weekends I was out and the night time temps dropped into the low 50's and high 40's. the heatpump on the atwood was busy and noisy, but it kept the coach up to temp.

there might be an issue with the controller board on the top side of the atwood causing extra cycling. I am waiting to hear back from Atwood on my Unit. It looks like Billy got his fixed, and it is not cycling crazy.

I will say though, that the current cycling of the heat pump, is not much different then the same noise as my old original sol aire. My sol air furnace turned on and off alot too, because of poor insulation and running it in really cold temps. So the coach did not retain much heat.

I tried to compare the heat pump in my coach, to the heat strip in the dometic in our fiber trailer. I firmly believe that the heat pump puts out way more heat then the heat strip. But the heat strip obviously will work in freezing temps, where the heat pump will not. But I also think once you get to that temperature, the heat strip will not keep up anyway. (it might take the chill out, but will not keep the coach at 65-70 degrees when it is 10-20 degrees out).

I had a Penguin II on my coach and replaced it with an Atwood. As others have mentioned the Atwood is much quieter. My Penguin was leaking inside due to the Styrofoam condensate tray inside having cracks in it. I have to admit the low profile unit sure looked better as the Atwood is a large and high unit (but more BTUs).

Atwood put out a news release last year announcing a new low profile unit but I do not know if it is available in the USA: http://www.aircommand.com.au/news.php?news=44

Johnny,

Wow two A/C's on a 23"! You should be forming icicles!

One thing I'm curious about on your 23' is how far aft is the 14"x14"
cutout? In other words, what is the distance between the hole and the rear
of the coach?

Holy cow! It is a good looking unit -
http://www.aircommand.com.au/cmsfiles/pdf_files/Ibis-3.pdf

This is their 240v/50hz unit, but at 222mm or 8.75" it is definitely a low
profile!

I'm emailing them now...

How about using the spare tire mount and leaving the spare off. You could always use a fiberglass spare tire cover to hide the outside unit

There is nowhere to hide the condensing unit. Maybe if you removed the propane tank you could work it in, but on the bumper seems unattractive to me.
