Ok - you all have me curious now. Can someone take a picture of their hitch for me? I think mine has a sleeve in it, but can't be sure (bought the truck used @ a year old). To me, it looks like there is a sleeve inside the receiver. Not sure if it normally has 2 walls. I know the simple answer is to measure, or try a hitch (I have not tried either...). Is the insert obvious enough I would know its there? i.e. does it lock in somehow, or attach with a pin or something that would be a tell-tale sign?
Follow up question - looking at the build sheet, my 2500 appears to have come with a class V hitch. I came from a 1500, and would only have access to that hitch/ball. Do the 1500's come with class IV I would assume? That would be easy enough to check when I get home.
