Custom gooseneck hitch welded on

I was thinking if the owner had the original pinbox and didn't modify, that I could ask for that too. Then I'd only have to buy a 5th wheel hitch.
Seeing as how he doesn't I'll have to buy hitch and pin box. I think I'm going to have to pass once again on another camper. I'm praying that something pops up in my price range soon! It's camping season!!!!!!
