Well, this is our EV

and this is where we charge it from. The EVSE is mounted in the front cabinet. 120 volt is fine as this is just a commuter car with only 120 KM of range. Really 120 would be fine for most people as an overnight 18 KW charge would still get 100 KM of range the next day. Fast chargers are getting pretty common out there. If the campground has a 50 amp 240 volt hookup you can always unhook your coach for the night or just run the coach off the 15 amp receptacle for the night.
Just for reference, one killowatt gets you about 6 ish kilometers in most EV's.
Going down the road you can rig an umbilical 120 volt from your coach inverter or generator.
