I thought that was pretty slow.

DC,
Same here. I've averaged 17 mpg with our 08 Grand Cherokee CRD towing our FC23FB. It's 23.5 mpg without the trailer.

I have been getting 10.5 mpg at 60 mph pulling my 02 Safari 25 with a 2010 Chevy 2500HD gasser. That is with E10 fuel. I get better fuel economy with non-ethanol gas.

Fuel economy ran 8.5 mpg hauling my SOB trailer which was a smaller lighter trailer than my AS. This was hauling with the same Chevy truck. This was averaged on 20,000 miles of hauling.

With my 2011 Silverado 1500, I get between 11 & 13 mpg. I can burn E85 but it only pays if the price is more than 15% lower than regular. Odd that the mileage is less when I cannot notice any difference in power.

The truck's computer changes things for the lower BTU content fuel. Power should stay the same or even better if it advances the timing a little to take advantage of the higher octane. Usually the computer changes things based on O2 sensor readings.

Pulled the AS to Jackson Center (600 miles) with my '11 Sierra HD/Durmax and averaged 11.5 mpg running about 70mph. I get about 18 when not towing. Effortless towing with the diesel. Total weight it 16,600 lbs. Trailer is 8800 (dry) and truck is 7800.

My 4x4 Suburban avg pulling my 32' AS was about 9mpg. Even with Hensley it was not as comfortable to pull as the Sierra.

We've towed our 2012 International Serenity 27fb from Portland, OR to Tucson, AZ (via Boise, ID and Las Vegas, NV - about 2,100 miles) with our 2011 BMW X5 35d. Fuel economy has been 16.4 mpg...not too bad. Unhitched fuel economy (highway) for the X5 is around 26 mpg. She pulls Ike a champ! You have to love that turbo diesel...

This is exactly correct!

05 Ford F150 w/5.4Liter returns a consistent 11 mpg at indicated 55-60 mph with the Bambi ... not bad, but certainly not the amazing mpg that many others are getting. Often we are under 40 mph going up passes; however, we have broken 20 mpg with the truck by itself! We shall see how the new diesel works out - keeping fingers crossed.

Now that is amazing...
Our average for a trip to CA last year was 11.1 with our "gas hog" 8.1.
Feel much better now...thanks for posting.

We pull our 19' Bambi with a 2012 BMW X5 35d (diesel). Have made trips Seattle-Whistler, BC; Seattle-Leavenworth; Seattle-Park City, UT. Average mpg has been middle 16's at 65mph or with some local stop and go (through Vancouver); and middle 17's at 50 to 60mph on highway. We could do better with a lighter foot on the pedal going up hills - will try that next trip...
Not towing, we average 26+ mpg with mix of local driving and trips to mountains for skiing.

Pulling our 28 foot International Serenity with my 5.9 Cummings we get 15.3 at 63MPH....like most diesels you ratchet up the speed much and you pay a healthy penalty in mileage. Paid $4.45 in Connecticut for diesel Tuesday morning....painful! Sure has brought me down to the speed limit....
