First time towing w/EQ, question

I got my Equalizer set-up and my wife and I went to a local campground with our new trailer for our first shake down trip.
I set everything up per the instructions, using 5 washers, and the truck/trailer are pretty dang near level.

I had to jack my truck up really high and still use the provided cheater to get the bars on. When I retracted the tongue hitch the bars were somewhat swayed.

Also, when making sharper turns I could feel the vibration of the hitch in the floor board of my truck.

Is it possible for these hitches to be set-up too tight?

I bet you guys thought I was going to ask if my hitch was supposed to be this loud It will definitely wake a campground up!
