We made our first long distance tow from Southwest Missouri to Ft Myers, FL with our F250, 6.7, Lariat, Crew cab, pulling a 35ft Sabre that weighs 10K dry.
I didn’t take it over the scales but I know by the time we loaded the RV with all our junk and the truck with two big dogs we were on the heavy side of our pin weight. I’m another one that wishes he had bought an F350, but maybe next time I trade.
Truck did great. I ran 65 Mph about 75% of the time but rarely over 68 Mph. I did this to try and help the mileage and things just didn’t feel as good when I when I pushed up to 70 Mph.
I changed the oil at 4200 miles right before we left beacause I didn’t want to have to worry about it in Florida. Ran about 75lbs in the stock 20” Michelin tires because of the weight.
I was hoping for a little better fuel mileage but I’m not really disappointed, just curious what others are getting under similar circumstances.
What is the truck doing or should I say not doing that makes you wish you went with a 350? I'm assuming this is a fifth wheel and are you using airbags?
Not being critical but that does seem like rather low fuel mileage . . . I would have guessed you'd at least be up around 12. Fairly flat route and not a lot of weight.

Diesel F250's don't have an excess of payload. I'm sure that that is what he is thinking about.
At 65 mph or so, ten mpg is about average regardless of weight, really. I pull a variety of campers, from 17 foot TTs to 42 foot 5ers and toy haulers. My observation is it has more to do with wind resistance than weight and speed is a huge factor.
If I go 65 to 68 I get around 10 to 11 mpg. If I go 60 I'll get around 13mpg, and if I go 55 I can get up to 15 mpg.
Empty at 60 mph will net me 19.7 mpg.
Yes this is a fifth wheel I am pulling. The GVWR is 10K, I assumed all F250’s were the same. Because of all the options included in the Ultimate package my combined weight of occupants and cargo number (yellow sticker) is only 1998 lbs. The 5er’s pin weight is 2K.
It’s not that the truck is not doing anything I need or want, it’s just if I had a 350 this number would be about 1000 lbs more.
I only getting a couple of inches of squat and have never felt it hit the bump stops. I have not added air bags yet. I’m considering lowering the rear ended with the 2016 blocks to bring the nose of the 5er down then adding air bags. I was parked next to an identical F250 with 20 inch tires but it was 15’ or 16’. I couldn’t believe how much lower it seemed.

I'm about 1k - 1.5k lbs less, but on a trip to Michigan from central MO last summer, I generally averaged between 10.25-11.25 MPG at the same speeds. Over 2500 miles (2000 towing) on that trip, I averaged 11.8 overall.
I took another trip to Johnson's Shut Ins here in MO and averaged near 13 on that trip. Speeds were generally 45-55 though due to the *****ty roads. Speed is an MPG killer with these big fifth wheels in tow.
I tow a 8K bumper pull toy hauler. My speeds are the same as yours, and i average about 12-14 depending on the terrain. Lowest was 10 when I towed to Dallas late last year in a 35MPH headwind.
I haven't gone long distances yet, but the towing I've done so far has been in the same MPG range the OP observed. I don't really consider it horrible given the frontal-area and weight of the fifth-wheel, but I'm not thrilled about it either.
I've been getting 9 mpg @65 mph and 10 @ 55-60 mph on a few long trips. I run with the tow/haul mode and engine braking on. Trailer usually weighs 15 to 16K loaded down.
