30 Amp VS 50 Amp
I know that problems will be caused if you try to run 2 A/Cs while on a 30 Amp service, but will there be any problem running 1 A/C & using the microwave at the same time & should the water heater be ...

I've run my ac, fridge, water heater and microwave on 30 amp connections many times, regardless of a 30/50 amp trailer.
Either there is far more to the story of flat out false. Something like the load supporting inverter or a load shedding device could make this work but standard stock 30amp RV electrical system won't handle this.
To the OP: One of the issues is the fridge, battery charger, electric water heater along with other minor loads come on and off in an unpredictable manner. You might get away with it one time if they don't come on at the same time or you might not.
Also, some loads (anything with a motor) try to draw the same wattage regardless of voltage. If voltage is low, it draws more amps to get the same wattage, so another variable that might let you get away with it one time but not the next.
Bigger issue is 30amp is not a continous rating. Continous is limited to 80% or 24amps. If you search online, you will find many stories of burnt power connections because people push for every last amp. Some of those turn into RV fires.
Microwaves don't run for long, so it's usually better practice to shut the air/con down for a few minutes while you microwave the leftovers.
