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.

so you are saying that if I run 2 aCs, water heater, etc., and exceed my 30 amps and it trips that if I do exactly the same with a 50 amp rv in a 30 amp outlet that that is somehow worse?

What I and others are trying to get through to you is this: A 30 amp rig will probably pull about 25 amps max. That's the way it is designed, and within the safety zone of the 30 amp outlet. A 50 Amp rig, wired the way adapters are will, under normal use require probably 50 to 60 amps or more. In other words, you're a overload looking to happen. With almost no effort, you can and will pop the 30 Amp breaker, stress the outlet and the 10Ga wire. Unless you are very miserly about your usage, you will not only strain and damage the campsite's equipment, but you will possibly drag the voltage down and damage your own microwave, TV, and AC. So please don't do it!
