For 30 amp service, use the rule of three, as in 3 is too much. AirCon, water heater, microwave. Use only two at a time. Often the three might play well together, but when you throw on another heating element of any kind (toaster, coffee maker, electric skillet) or the DC converter, it’ll often trip a breaker.
Thats a great rule of thumb . Anyone doing otherwise , usually will not get away with it . As said 22 years same park ,same 30 amp service with four different RV's ,and its always been the same . run two ,can't run three usually .
