Plug or unplug that is the question

When spending only one night at an RV park and are connected to power should you pull the 7 pin cord from tow vehicle thanks for your input

  • Hummmmmmmmm---lets see

    You connect to 120VAC CG power which powers the 'charger' that maintains the battery....12VDC

    Real question is:
    Do you unplug the umbilical cord when parked overnight W/O shore power?

    I do..........cause the truck batteries are tied to trailer batteries thru umbilical cord which could end up draining both battery systems

    Some vehicles the 7 pin is not hot when ignition key if off---some it is hot all the time
  • I never hook up shore power without first unplugging my 7 pin.

    Might be ok, but why take a chance? With all of today's hi-tech computer gizmobops in our vehicles, who know what back-feeding can do?
  • I generally do, tho I rarely do not unhook. I at least use the jack to level the camper. But I pull the plug and unhook the chains for no particular reason.
