If I were you I would call the place where you bought the camper from and ask for help there as well. A lot of times they can look all of the info up for you and let you know if it is a good idea to pull that much weight with the type of vehicle you ...
I dont know if this is any help, but I am a huge fan of the 5th wheel hitch from Andersen Hitches. It is super light weight and easy to install. Let me know if you have any questions.
