I bought an 1989 d250 from a plumbing supply company and it has a Goosneck plate in the bed. Well I fliped it up once I got home and found it was a king pin like the one that is on a otr trailer they had a trailer that hooked up to the truck. I was wondering what I can do with what I have? I looked at it for a little and it didnt seem like I could thread the kingpin off and replace with a ball for a regular goose neck it loooks like I would need a whole different plate to make it work and i looked at the plate it is welded to the frame on the inside and outside of the frame. I dont have a trailer at the moment but eventualy I want to get a goose neck trailer. Rite now that kingpin is useless unless I flip the truck upside down and lock it into a otr tractor 5th wheel

 

try to get some pictures to help give us some ideas, cut the kingpin off maybe and install ball

 

some trailers where inverted 5th wheel,the hitch was mounted on the trailer not on the truck

 

Does it look like this:

Curious as I have seen this before and not seen the trailer side of what attaches to it.

ya it looks like that link ill try to get some pics of it

 

We have that same set up at work on our F-350, and they use the same inverted system on some oil field trucks. I guess the only real nice thing is you don't have the 5th wheel taking up space in the bed.

 

When you buy a trailer you don't have to go with a ball, you can go with a kingpin. Or if you find a used trailer the inner tube that you adjust for height just slide it you and replace with a kingpin one. They run around $200
