2018 Zinger 18RD towing question

[CamperNewb]

Hello Everyone, First-time trailer owner here. We have tent camped for years and decided we are too old to sleep on the ground any longer. Our tow vehicle is a 2011 Santa Fe with V6 and tow package. Trailer is close to our max tow weight. We have a load equalizer hitch with sway control. Just picked it up from the dealer yesterday. Here's my question: The ride when towing seems to be very choppy and it feels as if there is an ongoing push-pull between the trailer and suv. Are there adjustments we can make to the load equalizer to resolve this issue? Thanks everyone!
