20 amp service is not enough. You need 30 amp service.

Does that simply mean a new circuit breaker, or are we talking major
rewiring? I wonder if the dealer will buy that.

I'm no electrical expert, by any means, so take my advice with a grain
of salt. But I believe he means you need 30 amps in the house, in the
circuit you're plugging into.

But that may not be the case. If you have a dedicated 20-amp circuit (or
at least nothing else running on it at the same time) AND a heavy-duty
cord that's not too long, you may be fine. I used to run my Class B's
11,500 BTU a/c on a 15-amp circuit when we lived in our previous house.
No problem at all. I used a 14 gauge 20' cord.

However, it sounds to me as if the problem may be in the RV rather than
the house circuit. Like there may be something else on the same circuit
in the RV that's turning on and off, causing too great a load when it
comes on. Was there anything else (other than the converter) turned on
in the RV? Refrigerator, maybe?

I sincerely doubt that that is the problem. Every RV that I've ever seen
had the AC on its own circuit---for just that reason, I might add.

I think his problem is that he is plugging his trailer into a 20 or 15
amp outlet and the AC requires a 30 amp source. A 13,500 BTU unit takes
a lot of power in the heat of the day. When things cooled down, late in
the day, he was able to run the AC on the lower power source because it
was not working so hard.

Even I, the electrically challenged, understand not to run an AC when
there is less than 30 amp service---and unless you have a power
monitoring system that automatically does the switching, you don't run 2
ACs without a 50 amp hookup (or the gen set)

The trailer is plugged into a 20 amp outlet, which is the same amperage as
the circuit breaker in the trailer.

Now it's a mute point. The AC has been running fine for the past three
days. I'm feeling like Peter, the wolf guy.
