I still don't quite understand the use of two 2,000s. one yamaha EF2400iS should run the AC, is lighter than 2/2000s, cheaper, etc.

There are a lot of threads about the 2400 watt Yamaha and A/Cs. It can be a lucky throw of the dice if it works or not, mainly due to the inrush current, then the inrush current from a compressor with full head pressure. Even 3000 watt generators can be dicey with some 15k A/C units.
The two 2000 watt Honda generators run at 3500 watts, which is enough headroom to handle all the locked rotor amps most RV A/C units can throw at it. If one needs more wattage, Wise Sales sells a three-way parallel kit. If one needs even more wattage, YouTube has people running four or more Hondas in parallel.
One fact I remember from a friend of mine who does marine generator service (Kohlers mainly) -- a generator runs best at around half load. So, after an A/C starts, a 3000 watt generator is at a good point to be at, similar with two 2000 watt generators.
