We do have the means for you to swap out the electric brakes currently on your 2018 Jayco Eagle 321RSTS, like part # AKEBRK-7-SA, so that you have a hydraulic system that is compatible with the electric brake controller on your 2016 Chevy Silverado 3500 Duramax.
I recommend going with either the Dacromet # K2HR526D or Dacromet and Stainless # K2HR526DS Kodiak Disc Brake Kit (1 set per axle), which both have a 6 on 5-1/2" bolt patter, and then the HydraStar Electric Over Hydraulic Actuator Kit for Disc Brakes # HBA16-252-82. This gives you everything you need aside from the Adapter Module # HBA-CAM if your brake controller is the OEM one. The module is used so that your brake controller can communicate with the Hydrastar EOH actuator.
This is the absolute best setup for trailer brakes because you get the power of hydraulic disc brakes and the accuracy of electric brakes. I have attached some videos that you can check out.
