You really need to study the owner's manual to determine how your

trailer is wired.

Thanks.

The owners manual is a piece of crap. The first half is a list of all
the 'don'ts' so they don't get sued, and the second half is so generic
I could use it as the manual for my boat trailer.

That is not unusual. Most of the RV, camper tailer manuals are the same.
You'll find out over time just by experimentation as to what runs off the
inverter and what doesn't.
You can also get faked out though. For example, we had a Chinook Glacier
RV that had a super-dooper, relatively high capacity inverter. But, it also
had a sensing unit in it that detected the presence of external shore power.
If it existed, the inverter internally bypassed it's own output and
distributed the shore power to all outlets (except the AC and Microwave).
If no shore power was detected, it switched over to it's output to supply
the same outlets with 120vac. It took me a while to figure out what was
going on and I had to carefully study the supplied inverter manual to
discover this.

Usually the microwave does not run off the inverter and is not hardwired for
power, meaning somewhere you will find it is plugged into a dedicated 120vac
outlet. That would be a good test point to measure your supplied shore
power voltage while the AC unit is running.

That's probably in the cabinet right above the sink. I'll be picking
up the trailer later this week and will check it out. Thanks for the
help.
