If your trailer plug is a seven terminal plug (TT has brakes) You should have 12 volt power to the camper battery through the top right terminal (looking into the socket on your tow vehicle, the black wire at 1:00 position). If the pop up is equipped with a power converter, the battery will charge when plugged into shore power. I'm assuming it has a 30 amp power cord. I'm no help on the crank, sorry.
