Unhooking electric from tow vehicle
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?

The trailer battery charge line power from my truck is thru a relay that is activated when the ignition is start or run. Other wise their is no power to the trailer. However when the tail and brake lights are active when the truck lights are on. I believe all late model trucks are that way-- at least that is how Ford is wired. If the truck is running while hooked to the trailer and the shore power is connected to the trailer, the trailer battery charger is active which will not do any damage to the truck alternator or visa versa. The alternator/charger will see a net reduced load which does no harm....
