I replaced my entire hitch and bumper with a Ruenel that is rated for a 20,000# pull and 5,000#+ pin weight. How's that for heavier duty? Pictures are in my gallery.
I've never owned one, but I've heard the Titan V is a good unit. The downside to the Titan I've heard, is that it will mount under your factory hitch. If that is not a problem, that might work for you.
Good Luck!
