Hi Sled208,
If there is only a 30 amp shore power supply, limit the total energy use to 80% (24 amps or about 2900 watts). It may be necessary to monitor the voltage. If it drops below 107, turn off some of the loads.
A kill-a-watt meter is a useful piece of kit to have.
My roof air, when it is HOT and has been running for hours goes up to 1900 watts. That leaves me with another 1000 watts to use for other items.
A possible third alternative, if you are in a dry area such as Arizona is to use a "stand alone" swamp cooler.

Thank you all for responding. I'm sorry if I'm not responding to each suggestion but I value everybody's input. Here's a big issue that I discovered this weekend. The electrical hookup at my spot only has a 30amp plug. Nothing else. I was sure there would be a separate 15 amp outlet but there is not. I think that limits me specifically to replacing the existing unit only?? I don't know if I can run one of those portable units even?
