EV use the 30 amp 110V?

Do you explain to the staff how much extra power you are using and what it is costing the park? Particularly for government parks, they may have no idea and effectively its driving up the cost for your neighbors.

If it's one in a thousand sites, your neighbors will never notice but when it hits significant numbers they will bear most of the cost as the park recoups power costs .

Do I explain? No. But EV’s are common here. Many times the park staff are driving them too so I’m sure they know what’s involved. And keep in mind that on 30 amp sites which is mostly what we rent it’s either the EV or RV not both so consumption isn’t that much higher. Probably 30 or 40 kWh over a few days. There are occasionally up charges although we have never been charged additional fees on a 30 amp site. That’s just luck of the draw though as I know some do. In quebec we stayed in a park that had signs indicating EV/RV combos had to rent 50 amp sites but there were none available the 5 nights we were there so he just told us to make sure we only plugged in one thing at a time. He didn’t charge us anything extra. We charged the first night and then topped up the day before we left.

We are seeing more and more parks put in a couple or even four centralized. 8 kw EVSE’s for charging and they just indicate that any EV charging must be done using those EVSE’s (Charge stations) and not on the sites. Some are stand alone and complimentary and some are networked usually thru FLO and typically charge a dollar or two an hour based on speed. On our last trip there were two new FLO units at the shower house which was maybe 4 or 5 sites from our site. I think it was 2 bucks an hour. We got set up on our site and I drove over and plugged in. It was all charged up by bed time.

If they provide dedicated EV charging stations, that's a different ballgame as the owner/manager has made a conscious decision to provide the service. If they spent thousands of dollars installing EV charging stations, I can buy the argument, they should inform themselves.

But in normal usage: Presuming the staff has any clue is wildly optimistic. If they are staff vehicles, they likely never see the bill. If you highlight the amount of power you are consuming and a rough estimate of the cost...a much better chance it gets back to the owner/manager who then can make an informed decision rather than just flying under the radar.

As far power consumption on a 30amp being similar...on a hot day, we are pulling around 12-14amps when the air/con is running and it typically cycles dropping to 3-4amps when the air/con is off. You indicated your telsa is set to pull 24amps as a baseline and presumably does that until the batteries are full:
- Let's say RV is 16hr at 14amps + 10hr at 4amps ~ 31kwh
- EV is 24hr at 24amp ~ 69kwh
- On a cold day (no air/con), RV only is ~ 11kwh and the resulting cost differential is much higher.

That's an extra 38kwh (best case scenario) and won't fill the car if you are coming in empty and splitting off some of that power for RV use (even more if you use the 15amp for the RV while the EV is plugged into the 30amp as you showed in one of your pictures). Works out to around $10 extra at $0.25/kwh. If you have a 200site park and 25% are doing this, that's an extra $500/day in electrical consumption.

Yah some good points. But a couple of counter points.

-When I am hooked to 120 volts our heat and hot water is 120 volts so that’s an additional load. (Our trailer uses boiler heat and hot water).
-On a typical 3 or 4 day stay we typically only charge one of those days. Or maybe a little bit the night before we leave to top up.
- I have never arrived at a campground with an empty battery anymore than I would arrive with an empty gas tank. So i am never charging from empty.
- Most campground owners understand exactly what kind of consumption and draw an electric vehicle is. They are very common here. Those that are concerned charge a fee. It’s not uncommon although as I said so far no one has charged us anything on a 30 amp site. They have on occasion directed us to certain sites though so maybe they have a technical reason for doing that.
- Those that are uncomfortable with any charging can simply not allow it. It’s nothing we have ever run into but we have heard of it. It’s best that they put that on their website though so people can make informed decisions.

As I said, generally speaking most campground operators are very accommodating and many have gone out of their way to insure a good charging experience, and yes sometimes for a fee.

Hope that helps.
