You may not have seen that many dedicated electric car charging outlets, but I bet many of the RV parks you&#x27;ve stayed at have a 220 V &#x2F; 50 A NEMA 10-5 connector, which can give you about 30 miles of charge per hour in a Tesla. Not a supercharger, but decent.<p>Availability of non-Tesla electric charging depends vastly on where you are. In the northeast, there are a bunch of places that have 2-4 EV spaces with a CHAdeMO connector which (anecdotally) are always full. So if you&#x27;re planning a trip cross-country, you basically have to stick to the interstates for superchargers.<p>If you have an RV, you probably think that traveling cross-country via only the interstates is a pretty bad way to see the sights though :).
