I do the pull test as soon as I back into the hitch, I put in drive and bump the jaws, then put back into reverse to make locking hitch easier. I also do a visual check to verify that jaws are closed correctly around the pin.

The reason I do the pull test with the weight on the legs, if high hitched and you put the pin weight on the hitch (my case 2,700#) it would be hard to pull out with all that weight on the hitch.
