Gjac, I think if you are towing a 22' travel trailer with a newer half ton truck, and everything is set up properly, you may be able to go without any kind of anti-sway hitch. However, I think it's better safe than sorry and would have some kind of sway mitigation in place. Virtually any anti-sway hitch would be appropriate for your configuration. IMHO of course. I would probably opt for the easiest to use in your case. I'm guessing that's maybe the Blue Ox Sway Pro or Equal-I-zer. Once again, JMHO.
