What is wrong with these numbers
Ok heres the deal. I just purchased a 2013 f250 4wd crew cab 6.2. love the truck. I went on my first long drive to Kansas from North Dakota and back. I was towing my travel trailer Jayco 267 30 ft 6500lbs. truck is all stock and has 373 gears. My average MPG for the entire trip was 7.8 mpg for 2300 miles 1950 miles of the trip I had the camper attached. i ran 87 fuel every fill up. I'm not disappointed with the power the truck has but I'm confused to why the mileage was so low. I never hit over 65 MPH and ran constant 58-63 MPH. Is this low? Ive read tons of post about guys towing 10k lb fifth wheels who were getting 9. Disappointed to say the least. Whats wrong? my 1500 ram averaged 10.5 with the same load with 392 rear end.

I'd say that's low. I get 11 or 12 while towing. With 3.73
You could have been fighting a headwind the whole way, or your hubs might not be releasing. Definitely bears looking into. I assume tires are properly inflated?
It also occurred to me that you might have dragging brakes, either on the truck, or on the trailer.
Corrosion can be a problem on the caliper pins.

What size tires are you running? I hate my 3.73's every single time I tow anything. I have a friend that tows 7-8k camp trailer and gets 7-8 on I84(3.73's too). I have only done one decently long trip up and over the mountain pass and back home. I got 8 towing my 8k toy hauler. I'm not sure how anyone gets much better unless they have 4.30's. I barely get 10 in town.
I will say here in Oregon, the winter fuel must be gone because if I reset my mpg meter when I hit the rural hwy, I can finally achieve 15.....until I hit town.

It sounds a little low but I've don't have 3.73 gears so my mileage will differ when pulling. One thing to check is your fuel , next time keep a overall tally but check each tank and where you bought the fuel. I've had my mileage between tanks drop as much as 2 mpg pulling between fill ups going the same direction with the same road conditions using name brand stations.

Wind can be a killer......
I have noticed it impact me over 2 mpg when towing my 26' bumper-pull camper. I have achieved 10s, but fighting a nasty headwind, I could barely scrape 8 mpg.
Stock tires, wheels, lift/level is stock, but running 5 star tunes. I have not noticed any mpg improvement with the tune(s), but didn't expect any.

That seems low to me as well, but as others have said wind will really impact it.
Was truck loaded up with gear as well?
Hubs unlocked?
How fast were you going?
I have seen a big difference in mpg with just a few extra mph.
The 373s are not ideal for towing but they will get the job done as you said

Towing mpg
I recently towed a 26ft Travel Trailer (5,150 lbs) from my home in Dripping Springs (outside Austin) to Port Aransas Texas. Going down I averaged 6.8 mpg driving into a modest headwind. On the way back (with a modest tailwind) I got 9 mpg. Normal around town driving I get 11.8-12.5..
I am assuming you must have been fighting the wind a bit.
Truck is 2015, 6.2 with 3.73, 4x4, long bed crew cab, all stock.

I regularly get 14+ empty around home, 15+ on longer trips. With the 10,000# 5th wheel, I get 9-10. It's not a hot rod & I don't drive it like one. Slow down & enjoy the ride, it's a beautiful country out there if you take the time to see it.
