July 4th weekend I was in Largo, FL (close to 100 degrees, no trees) and used both my A/Cs on 30 amps for initial cooldown (13.5K and 15K) - no compressor cycling. Once cooled down the 15K keeps up so no need for the 13.5K unless things got uncomfortable. At that point turning on the 13.5K would again be for getting the temp down, so again, no cycling.
I can see no scenario when I needed to run both A/Cs where both compressors would have to cycle.

Talking about running larger 50A RV on 30A service, it seems some don’t think you can ever have too much of anything, but I disagree. Last week I helped analyze an RV that has two 15K A/Cs (and not even high efficiency) where the full 30K of cooling is not needed unless in Death Valley in July.
Bottom line is that both A/C combined exceed 30A campground service, so owner could only run 15K of air conditioning. Worse yet is that one A/C and microwave combine also exceed 30A.
Two high-efficiency 13.5K would be more than enough cooling 99.99% of time, and would allow running 27K of cooling instead of being limited to 15K on 30A service; plus would allow running one A/C while microwave is used. In this case less would be more.
