Pullrite will wrap around. And once completely engaged, no pull test is needed. It is failsafe by design. It cannot become dis-engaged, unless manually released.
But here's the issue. You really need to be absolutely sure the jaw is COMPLETELY AND FULLY engaged. If it is NOT...your connection is not safe. So for that reason, a good close visual inspection is recommended. And then a pull test.
If you want to buy a hitch so you can avoid a pull test, you might consider a gooseneck. Or get a travel trailer with a ball hitch connection.
