that article meandered off into the rare air area a bit. said if you hook a 50 amp RV to a 30 amp outlet that you were excessively affecting the campgrounds electric service. As far as I can tell, if you plug your 50 amp rv into a 30 amp outlet, you are "abusing" the campground's electrical service exactly the same as if you had a 30 amp RV. Can't be drawing more than 30 amps.
I think I would find some other "expert" to consult with.

I disagree. Maybe you didn't read the part about how breakers run at a given tolerance, and also about the part how a 30 Amp design doesn't normally come close to exceeding 30 Amps, but a 50 Amp design does. Thus it will be expected to exceed the current design of the plug, the wire, and the breaker. You can very easily damage the 30 Amp outlet, just as either a 30 or 50 amp plug can overtax a 20 Amp outlet. Running it until the breaker trips is overload.

A 30 amp trailer running ac, electric water heater (heating water), and microwave WILL trip the 30 amp breaker, just the same way a 50 amp running on 30 will. I have dome this several times on my old TT. There are also converter and fridge loads, on bad days it was AC or microwave plus the rest to pop the 30...
