If you are self-contained and bringing your own generator, you are not dry camping. You are electric only camping.
Your 2000 watt generator can supply a bit more than 16 amps at 120 volts. My Mr. Coffee draws 900 watts so I doubt if I could run it and a hair dryer at the same time with only 2000 watts.
Likewise the AC, the microwave or an electric space heater would all most likely need to be run one at a time.
When we camp with no hookups we adjust accordingly, we make cowboy coffee (grounds in the pot) on the stove. The frig and the water heater, are switched to gas, the battery is used for lights and water pump. The 120 volt TV, microwave and AC is out of service.
Two or three days is about our no hook-up limit so I have never fussed with a generator.
