Problem is the low GVWR (9200#)
GVW of 6900# leaves you 2300# before reaching GVWR
BUT
how much weight do you have on rear axle? And how much is RAWR?
Difference between the two is what you have for available payload.
EX: RAWR---6084
Weight ----2900
Payload----3184 (3200)
Subtract 5vr hitch weight, wife? and any stuff you have in truck (in door pockets,under seats, in bags etc)....400#
Now you have 2800# of payload left
12000# GVWR 5vr will have roughly a 2400# wet pin weight
You are under RAWR-----under rear tire loading
And you are over GVWR (6900 + 2400====9300)
Those mfg. published max tow and combined tow numbers are magical marketing numbers based on a 'base model with 150# driver and 20# cargo'
Real world is you run out of GVWR , RAWR and/or Rear Tire Load Rating LONG before you reach those magical tow numbers
Take your truck fully loaded camp ready (You, fuel, wife, stuff) and go to a scale and get weighed.
This will give you the real numbers......see how much weight you can add to rear axle/tires.
Use 20% of 5vr GVWR as a wet pin weight
Like in my example........12K 5vr
You probably would be OK with a GVWR of 12K as you would not be towing trailer at GVWR.
You will be over trucks GVWR.
