When it was newer, my 1998 F-250 got 13-14 mpg, when pulling a 2 horse bumper pull, with two horses in it, at highway speeds (out here, that's 75 mph mostly) and including Rocky Mountain climbs and descents.
These days, that truck has 170,000 miles plus and under same scenario as above, is getting about 10 mpg. Not towing, average about 45 mpg between 'around town' and highway, is about 13 mpg.
Edited to add...it's an automatic. I much prefer a manual but hey, got a good deal on it. In comparison, my previous truck, a 1985 F-150, was a manual, got 12-13 NOT pulling when new and about 10 when hauling. But, after Jiffy Lube had to buy me a 'new' (rebuilt) engine, well, gas mileage went down. And in its advancing age after we moved out west, one did have to pedal hard going up the 'hills.'

What make and model do you have? 2001 Chevy 2500 HD, 8.1 liter 4x4 (there's the problem!)
Automatic or manual? Auto...good luck finding a stick
Diesel or gas and which engine? Gas, 8.1 liter
What year? 2001
MPG highway and in town? 8.9 in town, somewhere around 11 highway
MPG highway towing? Unknown, haven't towed on the highway
What are you towing? 2H BP, dunno the weight offhand.
That being said, it's an awesome truck. It'll pull a house down if necessary, AND I can out accelerate anything but a sports car. A true sports car, riced-up Hondas need not apply.
My BF's truck is a newer (2007? 2008?) F350 with a 450 rear end, dually, and it gets about 14 mpg regardless. Also a nice truck...but I like mine better.
ETA: I get that 8.9 mpg and I drive like a granny most of the time.

2002 Ford F-250, gas, V8, 4x4... I get 15 MPG consistently in everyday freeway/around town driving. I was getting 13-14 until my husband bought me some fancy new air filter (K&N?). I commute 30+ miles each way to work and drive about 70 MPH most of the way. I think 15 MPG is pretty good for a big ol' gasser truck. Who knows what might happen to my mileage if I drove slower?
I have a 2H steel horse trailer with a dressing room. I almost exclusively trailer very, very locally (only a couple miles round-trip once a week most of the time) or around town and maybe on 50 MPH roads, but not the freeway, so I can't tell you what kind of MPG I really get when towing, just less than 15 MPG! I haven't trailered a long distance in a long time.
'98 F250 diesel (powerstroke 7.3) 4x4 extended cab, long bed, automatic. If I keep it at about 65 mph, it gets close to 16-17 mpg on long trips since we installed an air intake kit, which added a couple of mpg. If I'm going 70+ it easily drops to 13-14 mpg. That's pulling a full 3H gooseneck slant. I've never kept track of unloaded mpg because I drive my car (also diesel-44mpg!) most of the time.
Now my old Chevy dually with a 454, that was a gas hog- 8mpg, loaded or empty!
Friend's newish ('05 maybe) Dodge diesel, 4x4, manual transmission, pulling my trailer loaded gets almost 20 mpg according to his onboard fuel dohickey, and I'm pretty sure he's traveling at 70+ mph.
2009 GMC Sierra, 4x4 1500 Series with the 5.4L flexfuel engine. I get 15.6 consistently - there is a function on my dash that tells me. That WAS a good amount of highway (30 mins to from barn) mixed with local, and towing 4x a month, 20 miles each way. I tow a 2H slant/stock combo with one horse (steel).
We moved last week and I will do much less highway (now 5 mins. from barn ) so we'll see, but I LOVE this truck. Tows great for my needs.
Be very wary of factory installed "milage computers." Their accuracy ranges from spot-on to wildly innacurate. The only way to get a true milage calculation is to keep track over a half dozen tanks or so.
What make and model do you have? GMC 2005 Duramax 3500 single back wheels, king cab, long bed, 4 x 4
Automatic or manual? auto
Diesel or gas and which engine? diesel
What year? 2005
MPG highway and in town? i get about 18 mpg
MPG highway towing? i would guess about 15 mpg
What are you towing? a 2-horse straight load gooseneck with tack
love love my truck, i'm happy with the mileage i get. my last one, a 2002 Duramax 2500, was even better on fuel! (less heavy i guess). did have to change the injectors under warranty, but that's all.
2002 Ford F250 7.3L turbo diesel. Automatic. 4WD. I also have a towing chip and a cold air intake. I get about 20-24 not towing, 15-19 towing a 3H aluminum slant (I get around 15 w/ 3 horses, 17 with 2 horse ect)
I drive nice also low rpms (except in the mountains) and i always go the speed limit if not slower.
Depends so much on engine size, gearing, driving style, weight of towed vehicle, etc.
My 2005 F350 4WD set up for towing 6L diesel gets 15-18 mpg pulling a 6500# trailer at around 55 mph.
But go a little faster than 65 mph and the fuel gage starts to drop due to the gearing being set up to tow rather than race. However, we rarely tow over 55 mph.
And HOTDAMM! the towing gearing makes it hot off the line. think skeeert rabbit.

Our automatic, gasoline 2007 F150 4x4 crew cab, 6 1/2 bed, did go 19.5 empty, average over about 8 tanks, by hand measure and it is what the counter in the dashboard tells me, so it is rather accurate.
I drive consistently 69 m/h on the expressway, 55 on side roads and not over the speed limit anywhere, sorry, tailgaters.
You can't push me, but you may pass me, I will make room for you.
Then that dropped these past two months to 17.5 and I asked our mechanic, that told me all vehicles dropped up to 2-3% efficiency since they started to sell the new gasoline formulations with more ethanol.
He ought to know, he has some gas stations also.
Pulling our 16' steel gooseneck with two horses these last 800+ miles, we averaged 13.5, half of the trip was kind of downhill, half uphill, but no serious mountains.
Remember also that comparing older models of any brand to the newer ones is like comparing apples to oranges, close, both are kind of round, but different in important ways.
What make and model do you have? Ford F-350 Dually Automatic or manual? Automatic Diesel or gas and which engine? 7.3L Turbo-Diesel What year? 2003 MPG highway and in town? Best hwy was 20mpg - North Atlanta to St. Augustine, FL and around town for the week before filling up. Varies between 17 and 20 usually depending on terrain. Normal in town is about 15 to 16 mpg. MPG highway towing? Last weekend we averaged 10 to 13 mpg going to pick up a horse in FL. Once we hit the highway I typically keep it between 60 and 75 mph, depending on the local speed limits, flow of traffic and construction zones. Construction zones sometimes slow us down to 45 to 50 mph. Safety first. What are you towing? 4 horse head to head Sundowner (7500 lbs empty) Sunlite 740
We love our truck. I'm looking for another one to trade our Excursion in on that also has the 7.3.
