If pulling 24 amps through a TT-30 or 40 amps through a 14-50 trips a breaker, then it's the host's fault for the campground having a shoddy electrical system, not the truck driver's fault.
Lol in what world? Campgrounds routinely have next to no funding, if they even have power pedestals I wouldn't expect them to be wired for anything more than an RV.
Charging a truck does that? What's that campground going to do with someone plugs in their 50A 43 foot-long tour bus RV?
(I'm sure there's more to the story, and the details aren't important, but if charging a vehicle is tripping breakers for the whole campground there's something wrong.)
Yeah, probably not your typical campground, now that you mention that detail. Still, something seems off, but here I go down a rabbit hole that isn't important to the original comment.
