Yah some of that pencils out Valhalla, but I would think we are typical EV RVers and our daily consumption at a campground is probably quite a bit lower than your estimates.

Here is a graph of the first 31 days of our last big trip. Roughly 7200 kilometers pretty much 90 percent towing (didn't track that) The blue is home charging (there wasn't any as we were on the road), the red is supercharging and the grey is other charging such as driveways at family, campgrounds, touristy places that had free client charging etc. But it will give an idea of why I say that for us a typical charging event at a campground was probably less than 25 to 30 kwh. The Tesla APP is the source of the graph. All funds in Canadian currency.

Sounds like you are checking in and making the campground aware of what you are doing. That builds a lot of good will and is the right thing to do. If they tell you not to worry about it, you've done your due diligence but as mentioned, when it's one nights charging per week, it's really not worth them bothering with it (50amp sites are typically a few dollars more EV or no EV).
Looks like around 750kwh (34%) was at campgrounds for the month. Assuming the Canadian average price of $0.174/kwh, that's around $145 worth of electricity that will wind up on the campgrounds electric bill.
Yah we always try and check just in case.
So yah, the 34 percent was all free but probably half of that was driveway camping at relatives and even some freebee touristy charging. Some tourist areas have free L2 charging for visitors. Usually at 6 to 8 kW rate.
And remember, if the EV is plugged in the RV wasnโt. Essentially we used more propane as a result. Really the economics didnโt play a role in the decision as I doubt the propane was much cheaper. What influences the decision to charge at the campground isi convenience. So, letโs say one pulls in with half a battery, itโs nice to be able to top up for the next day so one doesnโt need to plan a supercharge. More of a nice to have than need to have but it was a factor.
Of course we tow with an SUV. The economics and dynamics of EV trucks with batteries twice as big will be different. Should be interesting. I still say a surcharge is viable and a possible revenue source for the campground. People are willing to pay for convenience. And I think the โone thing plugged in at a timeโ rule will become an important rule to make it all work. Otherwise wait for the supercharger (or non tesla equivalent).
Jmho.

Maybe. But I can tell you from many days of EV RV camping that itโs unusual to get more than 25 or 30 kWh from a park pedestal on an overnight stay at a campground. And that is only if our trailer is unplugged. We have hydronic heat and hot water in our little trailer which means both heat and hot water use either one or two elements (selectable) to operate (or propane of course). Between that and the fridge Iโm pretty sure itโs drawing close to 24 amps or roughly the same as the car. The only difference is if there is a voltage drop in the park the trailer keeps drawing max whereas the car senses the voltage drop and automatically tapers current to either 18 amps (at 113 volts) or 12 amps (at 109 volts) ish. As soon as that happens we get a text indicating charging is reduced because of low voltage. It does the same thing if it senses the receptacle temperature is rising because of a poor connection.
Jmho but if there is a difference in cost itโs probably closer to a couple or three bucks. Really we have never checked. Just a guess.
Might be different on a 50 amp site but we have never camped on one yet.
As you show, the EVs will try to max out the supply. Even at the reduced amperage at 113v, a 20hr stay would be over 40kwh. Assuming 24amps at 120v, that's up around 58kwh.
Right now when it's a stray EV once a week, most owners won't even understand. If it ever becomes a significant percentage of the vehicles, expect park owners to get frustrated. Even if it's only $3...if you have 50 EVs charging every night, that's over $50k in extra electric consumption per year.
On a 50amp pedestal, it simply scales up. Also, most 50amp pedestals have both a 50amp and a 30amp...do the EV owners plug the RV into one and the EV into the other? If it's a small EV being pulled by a MH, the batteries may reach full and stop charging but if the tow vehicle is an EV, Say the new F150, pulling 120-130kwh is well within the capability of a 50amp outlet given an overnight stop.
Overloading the park system is a separate issue.
Of course, if it's a gradual shift, expect a premium charge for people camping with EVs to be gradually implemented or a prohibition against EV charging.
