Question for when pulling in a site for the night and not unhooking from your tow vehicle: when plugging into 30 amp service at the campground, should you unhook the electrical from your truck?

When plugging into shore power?

I guess the sky is falling folks would worry about a surge taking out both trailer and truck?

For one nighters, I don't disconnect the truck. It puts a bit of power into the truck battery but not too much, there's a lot of resistance along that route.

It's also neat if I turn the trailer marker lights on, the rooftop markers on the truck come on too.
