It should be located between the two through bolts that have the chains attached. The angle of your first picture makes it hard to discern the location of the pin of the pinbox. No, I'm not advocating turning the base around. Any ideas out there that aren't costly and don't include raising everything all the way up. Also currently when loading and tailgate is down there is only about 8' from rv, so not much to spare all ready and don't know if a shorter pin box would make me hit. I'm selling this camper ( I'm a fulltimer) in around 18 months and buying a big boy so i really don't want to drop 500-1500 in a new pin box that's shortest and more confined. And yes I can go up 3 more adjustments on fiver head and set up adj on pin box, but as you all know with the ram the fiver rides high in the nose to start and I really don't want to keep lifting up the front of the RV as the weight its all ready favoring the rear axle. No damage was done, but the back of my pin box is several inches below rails. I assumed ( i know assumption is the mother of all flub ups), that when i bought a ful size pu ( my last was a very narrow ram box short bed) that the pin box would rotate completely inside the bed w/o coming into contact with the bed rails.

So I thought I was golden, until I did a jack knife test to see how much clearance there was from bottom of RV overhang when it went over my folded up tonnue cover. I did have to lift it up one set of holes to get 7' clearance from RV overhang to bed rails. I've got the mopar 30k fiver puck system and it works like a dream so far.
