Correct me if I am wrong but this may be problematic for a 30A pedestal. Some may be wired in an either/or configuration (using either 30A or 20A but not both) rather than wired for total potential draw (30A + 20A).

Most pedestals I’ve seen have both 20amp and 30amp breakers so they should be able to carry the own load.
Non the less the pedestal has to be able to carry at least 50 amps to cover that breaker.
If the pedestal is just a 30 amp then you may just not be able to use the second AC. But in most cases I think you would work out fine.

Yes, you’re fine

Hi

If you are still shopping and are not (yet) tied to a specific trailer ....

Does the 23' fit your needs? Is a 25' or 27' a better fit in terms of what you want to do? Only you can answer that sort of question. It's more core to all of this than the number of AC units on the trailer.

Assuming that the 23' *does* indeed fit your needs, then one AC is what you get (at least from the factory). Pretty much everybody out there running in a 25' or shorter trailer is doing it with one AC unit. 27' is the traditional "break point" for two AC units from the factory.

My guess is that the sales guy had 23 and 27' confused. Indeed the "make sure it has two A/C units" is very good advice .... on a 27' trailer. People do get confused from time to time .... it's even happened to me

We live in the "Great White North" and have a single 13.5k A/C on our 25 + 2 Fantastic Fans ... during the Summer after we clean the snow off the roof when boondocking, we use the open the window technique to keep cool. The other day when the temp hit the mid to high 30's C (90's F for you folks below the 46th parallel) we found the single A/C to work great - no need for 2 A/C's

No you don't need two in my opinion and EXPERIENCE. I have a 1994 Airstream Excella 1000 34' and have a new Atwood 15K+ heatpump. It does very well in northern New Mexico and northwest Florida in temperatures in the mid 90's. It also uses much less amps than the other leading brands/models.

So yes in my case as we had just one once and when it failed it was not pleasant for her. We could have limped by on the 2nd if we had one Now I have two. But then we have a 30ft unit

No😎

AtomicNo13 · 07-17-2019, 12:44 PM

Not until you need two.
Better to have and not use than need and not have...

pontzdav · 07-17-2019, 01:33 PM

I have a FC30 with one A/C. It is sufficient up to about 95 degrees. Above that, 2 would be better. So, for me it all depends on what conditions you plan to be in. One A/C has been fine for us. We are in north USA in the summer and south USA in the winter.

gator.bigfoot · 07-17-2019, 04:17 PM

Most sites I've been on are all 30 amp or no power at all. So 2 AC's are a waste for me. I've found that 1 AC so far has been adequate even in Nevada in August (which I will definitely avoid).

AGraham · 07-17-2019, 04:46 PM

You want two units without a doubt!

Mike0392 · 07-17-2019, 05:47 PM

You live in Texas? Oh hell yeah get two!! I had 1 in my old box trailer and almost died in Baytown, had to buy a free standing to help.

Big Thunder · 07-18-2019, 08:05 AM

I'm an A/C tech and we purchased a new 25' Flying Cloud with 2 a/c's!
I would never purchase an AS, or any trailer/motorhome with only one ac.
We've been in areas where the temperatures were 100+ and while others
struggled in their rigs with one a/c trying to combat the heat, we were
very comfortable! You'll be glad you made the upgrade!

perryg114 · 07-23-2019, 05:48 AM

Consider painting the roof white what ever combination of AC's that you use.

I have a Flying cloud 23FB. Been testing it out boondocking since November.
Here on the Central West coast temps have been known to hit 100+ which it did today. On my prior days of 100+ I would wait till it got to 95° before turning on the ac. Big mistake. It took well over couple hours for it to "cool" to a tolerable 80° as the sun kept getting hotter. Essentially the AC had to fight off two heat sources. Inside and out.
Today I hit the ac when the inside temps reached 80 knowing ahead of time it was going to be 100°.

MUCH BETTER results.

I've been inside a comfortable 73° while outside it's still 85° with a warm wind.
Bottom line nip it early and don't wait to turn it on.

uncle_bob · 08-15-2019, 07:11 AM

Hi

Well, we're at a comfortable 70 degrees here, mainly because I have the heat turned on (it's still 54 out at 9 AM). If it makes it past 72 here today, that will be warmer than yesterday ....

You do on the Texas Gulf Coast when it's 102deg F in Galveston Island State Park.
Just saying. And most TX state parks have upgraded to 30 & 50 amp pedestals.

Context is important here. The original poster is talking about a 23' AS. These are also narrowing airstreams at 8' wide, making for a smaller volume overall.

For that model, a single A/C would be perfectly fine. An upgraded single 15k A/C unit would could turn the A/S into a freeze box.

I have a 27FB model which is >30% larger volume than a 23. A single high performance Dometic Blizzard NXT 15k unit,. I live in sunny southern CA. I find this A/C to be greatly performant and I often have to run it on low as it can really put the chill on.

I use my dual fantastic fans far more and would put more value on the fans than A/C. Especially again on a 23' ft.

Excellent point. That's another reason I purchased the 23' for it's narrower footprint. I have no problem keeping mine below 80(I usually have it set at 78°) when it's 103°outside.
The pic I had up their was a test to see how cold it could get when temps went to 100. As you can see it had no problem getting to 73. A tad too chilly for me.
