I'd say you need a little more tongue weight...
I have had a few rigs, truck and trailer combos.I am most fond of my current truck/trailer, and my Hensley. I have had the equalizer, the eaz lift and they worked good with the right tongue weight.
Two crucial things. The right tongue weight, adjustment of the hitch height, and use of sway control. None of which you can't nail down till you get it weighed.
I did all of that, and then invested in a Hensley. But that being said. Get it weighed. Go on a day when its slow so you can "play" at the scales. Get it right, tow it around and adjust, re-weigh, the
N tow it around.. Adjust. It took my three trips, about 75 miles in all, 25 each trip to find it..
In those 25, I have a 5% grade... A stretch that causes a porpoising effect, and flat land with a mild turn about 6 miles long.
Have some fun with it. One you get it right, it's great, towing setup right should be an easy drive.
