I have the Sway Pro and tow a 33' TT with my Ram Laramie 1500. My truck has 4 corner air suspension which I felt was a must have when I ordered the truck.
Most folks will tell you that your trailer should be slightly lower in the front when being towed and your truck level. Also, when you tighten your chains, raise the front of the trailer (with the truck hitched) several inches with the tongue jack. Now, tighten your chains to the degree that when in the normal traveling mode, your bars are parallel with the trailer tongue. This takes a bit of strength on your part to rotate the mechanism. I do not use the flat tool supplied by Blue Ox, I use a long breaker bar with a 4" extension and the proper sized socket to ratchet my mechanism until it latches (snaps). I end up with 2 1/2 chain lengths showing from the side after I'm locked in. I believe if you follow these guidelines you'll be happy with your setup.
PS- don't hesitate to PM me if I can be of any additional assistance.
