I have found similar:
2008 GMC 2500 HD Duramax Crew Cab Short Box- (Truck has approx. 17,000 miles and it has 33"x11" Nitto AT Tires)
Highway @65 20+
Highway @75 18+
Towing 32' Featherlite Gooseneck (loaded weight about 12,000 pounds) 12-13mpg (from VA to Sebring)
New Tow Vehicle:
2009 GMC 3500HD Crew Cab Dually- (Under 3000 miles)
Highway @75 15+
Towing 32' Featherlite Gooseneck (loaded weight about 12,000 pounds) 9-10 mpg (from NC to Watkins Glen)
I expect that the 3500HD will improve with some mileage but will not quite be as good as the 2500HD because of the added width of the dual wheels.

With my Ford Expedition 5.4 pulling an open steel wood deck trailer with an E class SC and tire rack with 12 tires I got 12.8 round trip to the Road Atlanta race and 13.7 round trip to Mid Ohio going 70.

My stacker is 10' tall, so can you say wind resistance? Fully loaded, being towed with the '03 Ford 6.0 I'm down to under 9 with the low sulfer diesel and latest emissions required reflash. Was probably 10+% better with the old fuel and original ECU program.) And that's at 55-60mph.
The one time I towed the yellow car up when I just bought it and still had Kim's open Trailex, I think I was still over 15 mpg @ 65ish.
(I never tow fast. And if you've had a towing accident, you probably wouldn't either.)

2001 Ford F250 7.3L Deisel with Edge controller installed:
Unloaded Hwy: 20-23mpg
Pulling 24ft enclosed trailer, weight between 9K-10Klbs: 10-13mpg
This is assuming I keep speed in check, below 75 unloaded and below 70 with the trailer. Things drop off quickly above that.
The Edge controller makes a significant difference in mileage. I run in Tow mode all the time. Without the trailer, mileage improved about 15%. Not sure with, never did before and after tests.

Tow vehicle: Ford Explorer Sport Trac 4.6l V8 with a six speed automatic
Daily commute (empty, mostly highway) yields about 18-20mpg.
With an open steel trailer + my car (~5000lbs), I get around 14mpg. I don't have a tire rack on the trailer, but put 2 spare wheels in the truckbed, along with assorted tools & spares.
I think the taller 6th gear of my truck has a lot to do with the decent mileage I get when towing. Plus I tend to keep the mph around 70 on the highway.
-Z-man.

Yes, the air suspension is very heavy and may contribute to the lousy mileage I get. The Audi V8 is surprisingly good in a heavy truck and for towing with it's decent torque, but it uses a lot of gas.
11.3 mpg is very good.

I got 13.6 (roughly 225miles/tank 16.5 gallons) in my MIGHTY non-diesel, non-dually, non-V8/V-10 Toyota Sienna Mini-van. Yes that's right, 3.3liter V-6 from CT to WGI and back that was the average MPG. Yet another advantage to having a light car and aluminum trailer

F150, Triton5.4, 4wd, 4.10 rear. Get 12.5mpg on a good day without the trailer. With closed trailex and lots of spares, I get exactly 10 going to the glen or SP. Maybe 11 without hills. Usually keep it to 70 mph or so.
Mileage sucks, but the trailer hardly makes any difference. The pickup is actually taller than the trailer.
