Hi Switz,
So in your unit, when you are at a 30 amp site, and running the AC, the fridge needs to be running on propane? And if so, does the change over to propane happen automatically when the AC goes on and off, or is that a manual process? I appreciate the info, as I have a 50 amp two AC unit arriving shortly.

The dometic should swap on it's own. I know our norcold would. But you had to have it set that way. You could, if you wanted to, set it to where propane (or electric) were only manual, or you could set it automatic.

That's interesting, I would like to hear how that works out!

The refrigerator has a power switch for on/off and a mode switch. One can select automatic switching between AC and propane or force the propane to be the choice or AC to be the source.

In a 30 amp situation, I want the refrigerator to be in the propane position so I can run other equipment in the trailer even though the air conditioner is cycling on and off. We can select which of the two air conditioners to have operational using the two zone thermostat that is part of the 50 amp option.

The Truma AquaGo Custom instant on water heater operates only on propane and a little 12Vdc to power the logic board. So far it works well and is easy on the fuel use.

Their basic model would not be recommended if the trailer would ever experience freezing temperatures. The custom model (next model up and only one appropriate for an Airstream), if the power to the logic board is on and the propane is on, will keep the water in the heater coils from freezing.

We are about 100 miles East of Yall. My House thermostat sets at 80 degrees, wife and I like it warm. With that said I wish our trailer had a second AC unit. Get a 2 AC unit, options are a wonderful thing. As Yall know high temperatures are one thing, add high humidity and it can get miserable. So using a FF to pull in outside air just don't cut it.

Yeah that's understandable! Thanks for your input, is very valuable. I've heard it both ways now so many times, I'm more confused than I started...

No need for confusion-
Get a 50 amp trailer with 2 a/c units.
I wouldn't have it any other way.

Unless you live in the north and travel in the southern states during fall, winter, and spring. We never turn our A/C on except during routine inspections to exercise it.

After reading all comments - 50amp will edge out the competition likely - especially if you want sub 75 degrees temps as stated

Get r done

Even if you don't use the second AC unit very much, it's a great back up when you do, or to allow alternate room conditioning so the unit above your head isn't running.

50amp capability is a blessing when you are using the trailer for extended periods and staying places where 50amp is available. Again, you may not use it all or much of the time, but when you do, you'll appreciate it.

The cost for 50amp and 2nd AC is only about 1.5% to 3% of the price of the new trailer, depending on the deal, and adds real value.

I feel the same way about buying the full awning option, as well.

Airstreams are such expensive trailers; if you're going to spend that kind of money on a trailer, why not spend a tiny fraction more and be able to enjoy all the goodies?
