New Duramax owner hitch question

If you are going to use a B&W Companion hitch, get the one that mounts in the pucks, not the bed mount that utilizes the gooseneck ball. B&W states that hitch is not to be used with your type of pin box. Andersen is out for your pin box.

My vote is for Trailer Saver BD5. High quality, comfortable tow, gear protection. Fits right in your pucks. Only downsides are weight and wallet assault.
