That is just way too much trailer for your truck.  Towing rating has very little to do with fifth wheel towing.  What is the scaled weight of your truck loaded ready to go camping?  Subtract that from  the GVWR of the truck.  That is how much room you have left over for hitch and pin weight.  Generally speaking pin weight will be 20% of the trailers ready to travel weight.  Since you dont have that yet, use 20% of the trailers GVWR.
Agree.
The formula for towing capacity is the GCWR of the truck minus the weight of the truck when ready to tow (includes everything...hitch, pin weight, passengers, gear, etc.
