You'll do just fine with a 16K hitch, and Curt makes fine products.

I have a B&W Patriot 16K hitch for my mid weight trailer weighing 11K lbs. dry. The quality of that hitch is superior, and I especially like the easy adjustability of B&W's hitches up and down, back and forth. And in one second, the fifth wheel half separates from the base for easy lifting. Any fifth wheel hitch in one piece is a handful to get out of the truck.
