Just can't wait for the day when six of these trucks pull into the campground and all plug in on one leg/spur of electric supply. All of the campers that lose their A/C because the EV's killed the electric.....just might cause an uprising.

Some CGs allready ban EV charging for at least 2 reasons and most will in the future.

1. Extra cost

2. NEC code derating, meaning the total CG power is limited to about 50% of the total power for all of the site CBs.

Example: One CG I was at had a 100,000VA transformer supplying 18 50A sites. The sites totaled 216,000VA or 54% derating. ie Each site on average was limited to 46% * 50A = 23A @ 240V or 2x 23A 120V circuits. ie EV additional charging could cause one of the main CG CBs to trip.

FWIW My house has a 51% derating.
