Travel trailer hitch
I've been towing a bumper pull travel trailers and boats around for years I've never greased the ball on the hitch. I'm looking at stuff all over the Internet saying that you should Grease the ball...

I only grease mine when I am trying to be sure trailer drops onto ball easily or comes off ball easier. I don't always get it perfectly aligned so a squirt of silicon will help it slide on easier. If I seems I have to jump up and down on tailgate of truck for it to come loose, I will give it a squirt.
