The thread lives--maybe all this will help someone, someday. After returning the defective Ford/Chevy adapter, I purchased one from a different source to avoid problems from a manufacturing batch. The new one tested fine with a meter and works fine after installation. Its main job is to provide load to fool brake controllers that don't have a hydraulic setting. However, especially desirable for Fords (don't know about Chevys) is a secondary effect of draining off the short voltage spike that Ford uses to ping the trailer to see if it is still there. Without something connected the Titan actuator makes a clicking sound that "Randy" said doesn't hurt a thing. When I added a couple of brake magnets, the noise reduced by half. When I removed the magnets and added the working Ford/Chevy Adapter the noise completely went away. So, a Titan hydraulic actuator is the best one for an RV IMHO, but one definitely needs to install the Ford/Chevy adapter on ALL Fords (and maybe others as well.)
The experience with the Ford built in brake controller and the Titan actuator is satisfactory. However, at some point I will likely try a P3 (since I don't have the Ford aggressive setting) to see if I can get a better balance between truck and trailer on light braking. Thanks to all for the input.
