If he's talking about the Reese Goose Box I have had one our fifth wheel for over 2 years now. Lot's of info about it, just Google it. It replaces the pin box and all that is needed for your truck is a goose neck ball and a couple of hook up points for the safety chains. It has a couple of shock absorbers and an inflatable air bag. It is the best riding hitch I have ever owned and that includes a few. Reese does list the frame boxes it will fit so he would want to see what box yours has.
