All of the above....

• Double check the camground box for breaker on
• Check the campground box for actual power at the plug - many of us have testers for this
• Verify that your cable is correctly connected at both ends
• Verify that your circuit breakers for the A/C(s) are on.
• Verify that you have 110vac in the trailer - the LED clock on the microwave is an easy check
• Thermostat properly set for cool, not heat, and temp set
• Some thermostats need the fan switch in a proper position

All of these things have nothing to do the the trailer, the manufacturer, the brand, the model, or any other outside influence with the exception of the power to the campground pole. If there's no power there, even with the breaker on, back to the office you go.

Also, it will help a lot when you are more familiar with your unit so that you know and fully understand which appliances are 110vac and which are 12vdc or a combination. As pointed out, the two appliances that you cited are not 110vac dependent and therefore not a reliable indicator of 110vac in the trailer.
