Lots of variables with OPs question. AC size, micro size, brand/type of converter/charger, condition of battery.
If the CG has newer pedestals, that have 30 and 50 amp plugs, they likely have more available power, than an older CG with only 30 amp.
In my case, a 15K AC, medium size/power micro, a Progressive converter/smart charger, and quality newer battery.
I often use my AC, WH, and fridge on electric at the same time, with strong power source, no issue. I will also run the micro a short time as well. I use a digital meter in camper inside outlet to know what power is available, and where it's staying at.
A good quality meter, that works great, and easy to read.
