I think the ratings are 300 pounds weight / 3000 pounds pulling.
For what it's worth, here's a video I found on YouTube. I started this at approximately 1:38 (or so) because the first 1:30 is an advertisment. I was always a supporter of "double towing" and saw nothing wrong with it, until I watched this video. I don't double tow, never have, probably never will. But this video gives a LOT of information I didn't realize about the trailer hitch, and the entire structure of the trailer. It's well worth watching and, if nothing else, gives a different perspective about using that hitch on the end of the camper.
