2 Shore Lines?
I am new to this forum, so please forgive me if I am not posting in the right place. I just bought a 1971 Overlander one week ago. I have not been able to spend much time exploring all if its systems yet, but one thing seemed very strange to me. When I raised the rear access panel to hook up the electrical connection (shore line), I found that the trailer had two lines. Is this normal? I did not have enough time to undo any other panels and see what they are connected to, so I figured I would ask the experts! Any insight into this mystery would be gretaly appreciated. Thanks!
