I always remove the hitch an ball as soon as I am done with it.

And if you use it every day, or two or three times a day?

Plus if it's on a car and not a bumper hitch, it's probably bolted to the car's frame and doesn't come off.

Of course, if used 2-3 times a day that makes sense.
I use mine twice a month.
Mine has a 2” receiver. Pull the pin. Out slides the ball. Throw it in the back. Done.
