To run an air/con, you need around 10-12amps continuous but you need 2-3 times that for a second to get the compressor turning.
You are looking at a generator rated for 2500-3000w to do that reliably. There are some after market modifications you can do to the air/con that help keep that 2-3 multiplier a bit smaller but most 2000w generators are only rated at 1600w continuous output, so if you do manage to get the air/con to start, you will be pushing that little generator to the max.
The plug isn't really an issue. A simple adapter will handle the 30amp plug and circuit breakers, don't pop instantly. So long as it starts, the draw should stay well below the 20amp outlet limits.
Particularly if you try to keep the generator at the minimum, you won't be able to run anything else without overloading the generator. You may have to add a disconnect for the battery charger and switch the fridge over to propane.
