When I brought the 5er home in April from the dealer, the 12v cable from the camper to the truck dragged on the pavement and wore through. I took a bungy cord the next trip and attached it to the notched tailgate. It pulled the connectors loose from the gooseneck because there wasn't enough slack. Any of you experienced campers have a suggestion how I can get the right amount of slack between the camper and pickup? I see the 18 wheelers have springs to act as a buffer between the trailer and tractor. Is there anything like that for sale to use with fifth wheels?
