I use the swing away trailer option constantly to store my boat. In my particular situation, I have to swing the tongue around to the starboard side of boat after removing the two pins from center and port side. I've heard that it's important to keep the permanent bolt greased. What is the best way to do this? Should this be done while the removable pins are in and then completely remove the bolt with socket wrench? Do you grease it the best you can while it stays in place? And what is the best type of grease to use?
