I needed to mount a 5th wheel hitch for my 1989 Holiday Rambler. The project went smoothly and took two days of thinking and a day to install. I bought a brake controller and the truck was already prewired for trailer. Be careful as when the ford brake light rail goes low it does not go open but to ground this requires a diode to prevent brake controller battery back feeding to ground. I am not sure of this but instructions did mention this so I put a diode in.
