I bought and installed a B&W Turnover hitch assembly on my 2008 D-Max Crew Cab Dually. I found the 5th wheel assembly on the local Craigslist for $300 and jumped on it! They are $700 new and this "used" one did not even have the paint worn off the 5th wheel plate I then ordered the mount assembly new for a little over $400 shipped. It went on easily, even though I was laying on crushed gravel :doah: This thing is a beast and is REALLY easy to use. It is very nice being able to remove the 5th wheel plate in about 20 seconds and have a flat bed surface for hauling whatever I want. If you can afford it, I would recommend one of these units!
