I use one quite often at SC parks we frequent. All of their sites tend to have 2-30amp breakers but no 50amp. I haven't noticed any issues running everything off AC. I even run the water heater off AC and not propane without any problems.
I also do not have washer and dryer yet, so that may make a difference. The air conditioners are typically our largest draw and both of them will run on 30amp with little else running.
