Recently purchased a new tow vehicle-2013 Silverado. The previous owner had installed an "Hopkins Agility" brake controller. On my first trip I noticed that every time I apply the brakes there is a jerk and then I think everything is working OK. ...
My previous tow vehicle, a 2006 Silverado seemed to have no problems with the controller in it. I am not sure if the problem could be in the RV brakes. I wish there was a simple way to point to either the controller or the RV brakes.
