Here you go- this fits your exact scenario:
What Can I Tow?Essentially, you have GVWR (9200) minus truck weight (6440) = 2,760 left over for the weight of the hitch and tongue/pin weight which is typically 10%-15% for a TT and 20%-25% for a fifth wheel and possibly your weight and any family not present (plus their stuff).
That TT will likely have a tongue weight of 880-1320 pounds (well under your GVWR).
A 10k fifth wheel will likely be 2,000-2,500 pounds.
Seems like you're pretty well set for being within your ratings.
