actually.. kind of..
The 50 amp RV hookup sites have enough amps at the site, but if everyone has an electric and plug in around the same time for their 2-3 hour charge I bet the fuse at the main panel would trip.
Admittedly it’s been 20+ years since I’ve done much camping but most NF campgrounds that I’ve seen had no electric at all.
But I used to travel at least 100+ miles before I turned off of the main highway then 30 or more on unpaved roads before heading up a Forest Circus road and past the established campgrounds a few more miles. Generally about 30 to 50 miles past the last gas station or power line.
