With a cargo capacity of only 985 pounds you are going to be running that puppy at max GW just about every camping trip. So we will use those numbers for tongue weight.
With a properly adjusted WD hitch, your tongue weight should fall in the 10 - 20% of full camper weight. We will use 15% as "optimum" but with careful loading that tongue weight can be moved a little back and forth.
"Curb" weight on the truck includes JUST a full tank of gas and a 150 pound driver. You will need to add for the WD hitch; your family; and any junk you want to carry in the truck. (Generator, gas cans, etc). All of the is PAYLOAD (of which you have 2080 pounds available). So, using that number we will say your you weigh 200 and you carry your wife, kids and dog for a "meat" load of 300 pounds. Your hitch weighs 50 pounds. and you have nothing else in the truck (yea I know, gonna be more).
So "out the door" camping your truck weighs 5564 + 330 + 50 = call it 5950 pounds.
Payload available = GVWR 7700 - OTD weight 5950 = 1750 pounds available payload (tongue weight).
6698 is the maximum it can weight so the maximum tongue weight worst case 20% is 1340 pounds. Loaded like this, you still are OK
At "Optimum" of 15% tongue weight is 1005 pounds. Still OK
At Minimum of 10% tongue weight is 670 pounds. Still OK
HOWEVER you need to watch the GCWR of the "combination" as well.
Since we are running the camper at max what is left for the truck to weight? Using your figures (17100 pounds) 17100 - 6698 = 10, 402
So the truck can weight 10,402 pounds WELL and safely over the trucks max of 7700 pounds.
So you can add about another 400 pounds of "stuff or people" to the truck and not exceed your safe towing range by my numbers.
So if I got the camper right, you are seriously " GOOD TO GO!"
Safe camping my friend!
