We bought the 5th wheel prep package when we ordered our F350 last year and are glad we did. However, when we picked up the truck when it arrived, I was disappointed in the cheesy plastic puck covers they provided. They come off anytime I slide anything in the bed. Anyway, I found these awesome puck covers for my truck. They are a little pricey ($129 delivered), but after getting them last week, they are worth every penny! I thought I might share the website I got them from with you folks. Here it is: http://www.fifthwheelcap.com/
