What are your experiences? Any secrets? Loading the trailer this week for a trip cross country and really want to know what to expect.
The brake controller uses an inertia movement to activate the trailer brakes and works seamlessly. There is a short delay in applying the brakes and having the trailer engage but you only notice it when you release the truck brakes and the trailer brakes releases.
A new development we experienced occurred after driving in a heavy rain. The 7 pin receptacle outlet on our truck slants upward and filled with enough rain water to short the electrical circuit between the light power and the brake power. When starting from a red light we noticed the trailer brakes were dragging ended. After a short time the brakes started dragging which felt like engine power problems experienced when ignition systems get wet. Since we were driving a diesel we stopped and removed about 2 ounces of water from the 7 pin receptacle and everything returned to normal.
