The solution is to manage the load. The trailer should stay pretty cool at least during the short time the microwave usually runs. Simply turn the A/C off when using the microwave, then turn it on again when the cooking is finished.
Your answer makes sense. I don't disagree.

However, you would think that when connected to shore power, this would not be an issue. After all, it's an Airstream.

By the way, during the event I described, not one circuit breaker tripped; inside or at the power pedestal.

Low voltage is common in RV parks/campgrounds. If you keep a voltmeter plugged in at all times (ideally, digital, but analog is fine) you'll see that many parks operate on the edge, regardless of how new they are, especially during temperature extremes. Just because they offer 50 amp connection, doesn't mean the underlying infrastructure supports delivery of the full voltage all the time (if ever). My rule of thumb is maximum of 2 major appliances in use at one time, meaning water heater, space heater, or microwave. Even at that, I often switch one of them off. When operating the AC (unusual for us), it's the sole appliance in use.

While I seldom use the AC, I never use it without using my Hughes Autoformer (voltage booster), and I always use the surge protector (ahead of the Autoformer). I've appended links below. I see that TRI also has a voltage booster.

Our Airstream trips the circuit breaker inside if the AC compressor starts while the microwave is in use. That happens enough to accept it as a given. This even has happened with our other Airstream too. Another circumstance that trips it is the electric water heater setting. Certain combinations of electric hot water heater, heat pump and a portable heater will likewise trip the breaker. Then I use the gas hot water heater. It isn't much of an inconvenience and I adjust my usage. Sometimes I use a surge protector at the pole and it has tripped.

It doesn't matter if you have a popup camper or a million dollar Prevost motor home. If you use more power than what is available, something is going to give. An air conditioner can draw up to 20 amps, no matter who built the RV. A microwave is going to draw up to 12 amps, again no matter who built the RV. 20+12=32. Pop goes the breaker. And if everything shut down without tripping a breaker, it sounds like a bad connection at the campground.

The Question:
Is the AS Power Center under engineered? Should I press for a better answer/more warranty support?
Every design is a compromise, cost, weight, how useful to the average owner. The 30 amp common RV electrical system used on most AS products works for most people most of the time, with some power management as mentioned in other posts. If Airstream equipped all their units with 50 amp power systems, you would not have the problem, but it would cost everyone more money, and not everyone wants or needs to use all of their power drawing equipment at the same time. Many people boondock and use minimal electricity all the time. For them, a much heavier electrical system would be a total waste.

A 50 amp power system in an Airstream might be a factory option, but as it is the factory decided to make a one size 30 amp system. Many owners would be unhappy paying for a larger 50 amp service they would never use. I know that I would not use such a system. In fact I removed the heavy bulky 50 amp service on a GMC motorhome I once owned and replaced it with a smaller, easy to manage 30 amp system.

Many thanks for the thoughtful replies!

It has been a great help.

I shorted the switch wires above the sink and just turn the thermostat on the AC down so the compressor cuts off when I use the microwave. This keeps air circulating but still provides enough current to run the microwave.

We're no longer staying. We are home, but were camped at Devil's Den. Petit Jean and Lake Catherine are close seconds when it comes to favorites by the way.

Just to let you know. I don't do much in the way of Missouri park camping. Arkansas state parks have my state's parks beat every which way!
Others have already nicely addressed the electrical load issue.

Glad you enjoy coming south to visit! Devil's Den is certainly one of the nicest state parks. Good hiking, and the caves make a nice cool place to stop and rest. Beautiful area.

I grew up in western Arkansas near Petit Jean and Mt. Magazine. Plenty of nice stuff there too.

That's what I was going to suggest, without the wiring part - just switch the A/C to fan only for a few minutes while using the microwave, and you'll probably never notice the difference.

Alternate solution: Next time try Bull Shoals White River State Park. We were there for two days a couple weeks ago and never had to run the AC, nice and cool by the White River. Aside from the mechanical hum of the park's sewage plant across the river, this is about as perfect a state park as I've encountered. Lows in the mornings next to the river were in the 50s.
