Hey, Ernest!

You certainly can do this! It's not going to be similar to a puck system but you wont have any rails in the truck bed. B&W has a unique set up but if you have an existing 5th wheel hitch you wouldn't be able to use it. With this you will actually have a gooseneck as well as a 5th wheel set up in one.

If you have a short bed you will want to get part # BW33QR
If you have a long bed then you will want to get part # BW93QR

Are you wanting to have better use of your truck bed when you're not towing?

@Ernest Hello again! Yes, part # BW33QR would come with everything you need from frame backets, hardware, the hitch itself, and even some pretty solid instructions.
