With that heavy of a trailer, it sounds to me that you will be over weight. Try this website it will allow you to plug in the various weights of your truck/camper and show you a safe weight that you can pull.

I just bought a 08 Ford F-350 DRW and using that site to do my calculations, it said that (with 20% margin for safety) that I can pull 12,640lbs. Yes, I can probably pull more at the expense of safety, wearing out brakes, transmissions, etc...
Hope this helps,
