You may think the rubber caps protect the plug, but they tend to hold the water in. That is the green stuff that forms when oxygen from the air or water comes in contact with copper. A thin coat of grease will help prevent copper oxide from building up. The ground wire should be large enough to handle the entire load do not depend on grounding through the ball. Make sure your ground wire, which is typically white, is securely attached to the frame on both the truck and trailer side.
