Very good advice from all. However, I would like to correct one small misconception you may have on the Reese Dual Cam WD unit. It is NOT one of the "best", but is one of the "better". There is a huge difference between the better WD units and the best ones. That said, the Dual Cam should be fine for your application.
Pay special attention to the trucks payload capacity and the trailers tongue weight. They must be compatible. Keep in mind, the trucks payload capacity encompasses everything you put in or on the truck including you, passengers, tools, equipment, and that Dual Cam.
Good luck
Ron
