Following is the entire Anderson statement that 'Murff' was referencing from the Anderson WDH Installation Manual dated 7-2019:
""Andersen “No-Sway” Weight Distribution Hitch INSTALLATION MANUAL
For all 4′′ Drop/Rise WD Kits AND all 8′′ Drop/Rise WD Kits""
"
Using the WD Hitch with late model vehicles that have electronic anti-sway"
"The Andersen WD Hitch features its own sway controls that are designed to auto-adjust to the load in your trailer and prevent trailer sway when installed properly. Unfortunately, some newer electronic anti-sway systems can misread the anti-sway efforts of the Andersen WD Hitch and the anti-sway system may actually cause the trailer to sway as the two systems work against each other.
These potential issues typically occur with electronic anti-sway systems that are designed to detect trailer sway and automatically use the vehicle brakes to help control the sway. Please note that this type of anti-sway system is different from electronic traction control, which does not cause this type of problem. If you experience this type of issue, you will need to turn off the electronic anti-sway in your vehicle in order to tow with the Andersen WD Hitch.
This issue is most likely to occur in 2011 and newer truck models from Ford, GMC, Dodge, and Chevy. Refer to your tow vehicle’s owners manual to determine if you have electronic anti-sway and how to disable it while using the WD Hitch to tow."
