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 grease mine. As already pointed out, weight-distributing hitches put a LOT of force on the ball, more than just the actual tongue weight. Since I got in the habit with our travel trailer and big farm trailers, I usually grease the lighter trailer balls too. It makes me feel better, but I agree that it is less necessary on the light trailers.
