Is that the kind of plug used in RV parks in the US, or do they use something else?
The first stop was at 3:20pm at the Pacific Border RV Park, they had a 50amp outlet ...We charged for 2 hours and got 48mi of extra range. We used about 12kWh @.08...
I think it is possible to stop at the Klahanie Campground and charge up for 2hours at 30amp and still make it, or only charge for 1 hour at the border, also the 40amp charger will lower the charge time to 45min.
RV parks have two common power hookups
30a/110v NEMA TT-30 plug, or "30amp" for short...
NEMA TT–30 is a 30 A, 125 V recreational vehicle standard which may also be known as RV 30. It is frequently (and sometimes disastrously) confused for a NEMA 10–30.
30 Amp campground connectors are only 120 volt. They only way to utilize these that I am aware of would be adapt it to the MC120 which would only allow 15 amp 120 volt charging.
I think the MC240 will work with an adapter like this. then a 2 hour charge up at 30a/120v would give 24mi range.
I have not tried this adapter yet, I dont know if the MC240 will like only getting 120v
an adapter like this....

50a/220v NEMA 14-50 plug, or just "50amp" for short.

So I gather you could cause a problem if you plugged that into a campground TT-30 by mistake.NEMA

---Due to the appearance of this plug, many people assume that it is to be wired for 240 V, but this is a 120 V device.
...Rarely on playa do people need 240v. RVs do not use 240v even though their plugs remind you of dryer plugs. ...
The above suggests that some RVs use 50 amp 120V service... I thought all the 50amp sockets were 240v not 120v... Is there such as thing as a TT-50?...Big RVs with two ACs have a special 50 amp plug. These are rare and probably not worth supporting in your grid. They do it using two phases, and even have adapters to let them plug into two TT-30s at once. They do not try to get 240v...
This RV adapter includes a 30 amp RV plug (TT-30) and a 24" piece of 10/3 cord that connects to a box with a 50 amp 125/250 volt NEMA 1450 receptacle. Made with UL Listed components.
CHEATER BOX
The Cheater box plugs into a 120-volt/30-amp and a 120-volt/20-amp source on separate circuits to give the user a 240-volt/50-amp output. This adapter will not operate on a GFCI circuit.

The biggest problem with these devices is... THEY DO NOT WORK
Unless you happen to be in a very very old park, most all parks today comply with the National Electric Code and of course local codes. these codes require the 15/20 amp outlet be protected by a GFCI. The "Cheater box" will trip a GFCI 100% of the time, every time, no exceptions as soon as you plug in the 2nd plug the GFCI trips
The only way they work is if you are in a campground that, due to less than 50% occupancy during part of the year, lets you plug into two sites

Thanks for that!, but why does it matter if they have 30amp or 50amp hook-ups? It looks like you are using a MC240, so I thought you would be limited to pulling <30amps regardless.
Moderator's note: Ongoing discussion about plug standards etc has been moved to the Charging the Roadster thread. Let's keep this one for the road trip stories.
By the way, my question got answered. The campground 30 amp connections are apparently 120V not 240V. So using a TT-30 adapter one would have to use the MC120@12 or 16amps, not the MC240 at 24amps+. So, yes, a Tesla with an MC240 visiting campgrounds really wants to find the sites that have so-called "50 amp" service. (Any additional responses should/will go to the charging thread)
