Opinion on a second AC

Greetings, Thinking of upgrading my 2018 19' Flying Cloud to a 2019 25' International RB Twin. What are your opinions on the extra AC and the 50 Amp service. We are in Houston and use the Airstream in mostly the South/Southwest USA

Thanks, TominTexas

Get it!!!! Second AC is a no brainer for the south. Better to have and not need than need and not have. I wish I had a second AC on my 23D as we travel to the beaches in FL a lot.

Get it.
Writing the check is a temporary pain, regrets are forever.
You'll get 50 amp wiring and never worry about running one AC and the hairdryer at the same time.
Each AC doesn't have to work as hard. Or if one fails. your trip isn't ruined.
You'll have ducted air, so you can run the bedroom AC while you sit in the living area and have less noise. (although I don't find the noise objectionable). If you set the thermostats at a slightly different temperature, the two units won't kick on and off together, and you'll hardly notice them.

And if do get it, get a 30A cord and connector. Around here most campgrounds are only 30A anyway and continually manhandling that 50A cord when only at a 30A site is a bear.
But having the 50A when needed is nice.

Here is why I really like having 2 AC units in our 31.5' 310 TD CLASSIC MOTORHOME. Ill use both units to cool the rig down to where we want the temp then turn off the front unit to reduce the noise level. The rear AC does a fine job of maintaining the temp once we've used both to get it cooled off. So nice to have that option because they are pretty noisy. At night, we will shut down the rear unit in the bedroom and run the front unit if needed. Works out well.

I just ordered a 2019 Globetrotter with the dual AC. Replacing my 25' International Serenity that is a trooper, but in hot Alabama weather it's rough with a single AC. Going dual AC was a definite must since we also want to head to Arizona and New Mexico in the next year as well!

I wrestled with the same question. Should I get the 2nd A/C? I decided for it and at first regretted the decision because of the 50A cord and hauling around something I didn't think I really needed.

But I am now so glad that I decided to get the 2nd A/C. We would have had some uncomfortable days without it.

So my vote is for the 2nd A/C!

Being lazy, I justified getting a 30 amp cord also because I can run it to the generator without pulling out the 50 amp cable! (They're available with a 50 amp female and a 30 amp male!) OBTW, about the first time you try to coil the OEM Airstream cable, you'll be replacing it also. Just because it's 50 amp doesn't mean it needs to be stiff as a bridge cable. Mine has found a home in the garage.

Other than cost, the only downsides are weight ( = it's heavy ) and the lost fantastic fan. In some layouts you loose a skylight and not a fan ( = even a smaller issue ).

The upsides are pretty major. Being able to chunk in both units lets you cool down the trailer *much* faster under normal conditions. If you get stuck in full sun / 100+ temperature / 90% humidity, one unit simply will not cut it, let alone pump down the trailer.

One thing we do a lot is to run the "not bedroom" AC unit at night. The noise is less and you don't get quite as much temperature change when the unit cuts in. We use a small fan to keep the air moving through the trailer.

One thing I'm experimenting with is a short 50A cable. You have to park so the power post is fairly close to the inlet on the trailer. So far that's worked fine one try out of two. The first attempt technically *did* work. Having the cord hanging in air between the trailer and post didn't seem to be a good idea .... Had I not been so lazy, a move on the trailer would have made it fit that time.

Lots of Fun !!

Not even a question. Get the 50 amp/dual air. You will not regret it.

I used to have a 25' with only one A/C and the rear bedroom would not get cool in the heat of the summer. That is one of the reasons I traded it in. Now I understand that the newer duscted air in a 25' makes a big difference, but not sure. If camping in the summer in the SE USA, get the 2nd A/C in anything 25' or longer .

I spent 25 yrs in LA and learned that I'm a heat-o-phobe. Trying to sleep when its 95 degrees at 2 AM just doesn't work for me. I moved to Seattle, where it's seldom over 80; maybe a day or two annually, which I can handle with some reluctance.

When I bought my 27FB, I got only one AC, as I knew I was not going to return to LA in the summer, or AZ, NM, TX, etc. Otherwise I would have gotten two. With your living in TX, I suggest that you get two, no question about it unless you're a true heat-o-phile. I couldn't imagine living in Houston. Nothing "wrong" with Houston; I just can't handle the heat.

We have 2015 ducted air 25 FB FC. IN Az. We are suffering. It is $10,000 at JC to upgrade to 50 amp and second air. We mived to AZ after our purchase. We definitely need the 2 nd air.
