When they checked the voltage was anything plugged in and operating?
My guess would be the voltage would drop to below 110 with AC running and converter operating for the 12 volts and charging the system Then you operate the microwave and it drops the voltage lower which increases the amperage.
I would buy one of the plug in 120 volt digital meters.
I am going to say they are not going to find anything wrong with your rig.
X2. AC and microwave draw would put you on the brink at least. If the converter was supplying a lot of 12v to lighting and charging the battery, you could well be over 30 amps. Why I like the Progressive Industries EMS unit I bought. The remote display constantly shows incoming voltage and the trailer's AC current amp draw in real time.
