On my trailer the plastic valve handles rounded off at the handle valve stem interface. I remove the handle and turn the valve stem with a wrench to the position I want and then reinstall the handle. The manufacturer should use a metal handle or change the design.
Disconnect the truck. 2 years ago my converter failed on an over night stop in cold weather. In the morning both of my trailer batteries and both truck batteries were depleted. Needed a jump start. My truck is a 2012 Dodge 3500.
