Well, it is what it is. I was happy with the figure though it does show that the truck computer is off. The Bully Dog was higher too. It could be the extra clicking at the pump but whatever, it came to 13mpg by hand.

Just thought I would tell you about my experience with my setup. I'm a first time diesel buyer and could not be happier with the towing ability and mpg. I tow a 1997 34' Classic and get anywhere from 14 to 15.5 mpg on average, and that checking it manually. A friend of mine has the ford with the turbocharged V6, and pulling a smaller trailer is only getting an average of about 10 mpg by his calculations. The last thing i'll add is that he struggles on any type of hill and unless I take my truck off cruise, I'll leave him behind just because of the power and torque of my Duramax.

That is good mileage for the weight and yes, you are correct as far as torque and diesels go compared to gas engines. My engine is on the small side of V8 and I know that if I ever got in the hills it would be slow going. I believe that is where my mileage would falter as well. That said, it would be able to pull it though. My power and torque is better than the 2V 4.6L as the HO engine 3V but no where near the power of the ecoboost.

Had to return to this thread after an exceptional mileage figure of 18.5! This bests my previous high of 17.1 I doubled checked the pump arithmetic over three tanks, to verify the car's computed display.

The following contributed to this exceptional performance:
- Really watching the analog MPG gauge, and adjusting right foot a lot
- Slower average speed of 60 MPH on US Hwys versus Interstates
- Southerly 15 MPH tailwind pushing
- Lightly loaded TV and TT, no water on board, or trip cargo apart from a camp chair
- Turbo-diesel propulsion, of course!

Towing my 27 Classic with my 2007 Durango (5.7 Hemi) on our last trip to NC I got 10.5 MPG on the return trip and 9.6 MPG on our way down stuck in traffic for an extra 2 hours.

I plan on upgrading to a Diesel Truck in 4 years or so as I only have 66,000 miles on the Durango.

I did have to adjust the Reese Dual Cam when I upgraded from the 25 Safari to the 27 Classic and changed the rear shocks to Monroe Sensa Trac.

Look forward to seeing you break 20-mpg.

Left out the big picture for your numbers. I might have already added this, but this is the order of importance:

1] Vehcle spec (in your case, combined vehicle attributes)

2] Climate

3] Terrain

4] Driver skill (lets call it "motivation" as to FE)

So, running across Florida or Louisiana (flattest states) with a TD tow vehicle with an A/S where the lash-up/tire pressures/loadings have been verified; in mild temps and with a driver trip-planning for the fewest acceleration/deceleration events and with a travel speed of below 60-mph, is likely to see the highest mpg for this RV type.

IOW, helps to add context. Driver skill comparisons are moot, but lash-up and trip-plans are not where MPG is considered important. Travel speed (different than average speed; both are important), climate and terrain are easy to ascertain, lash-up, TV tire presssure (and vehicle loading against individual tire weights) is more tedious. Gather the numbers and there won't be much mystery as to predictable fuel burn.

But, fuel economy is only part of the equation. Number of nights aboard is how to divide all expenditures, from both vehicles and downwards as to costs.

One can own a 7-mpg moho and burn less fuel for a given trip, after all, as it depends on so many factors just for that one trip.

We got over 20 on a short run in east CO but didnt count it. 30 mph tail wind on 2 lane roads where we could run at 50 +-20 mph.

Mpg would have stunk going the other direction.

The most memorable thing from that day? My blue boy got swiped while we slept...

We have a 1 month old Ram 2013 3500 Mega Cab, and 2012 Eddie Bauer 27FB. The terrain in Colorado (Durango, Mesa Verde, San Juan National Park, Rocky Mountain National Park), had us average 12 mpg over 750 miles. Granted we were going up mountains, etc.

On the flats (highway) coming from Denver to Colorado Springs on a previous pull, I averaged 19 mpg towing.

Its fun to watch, however I wouldn't trade it for the world. Now if only diesel prices would drop below $3. I had to buy $4.09 diesel in some small town :-(

Best to date has been 20.3 in a caravan doing steady 40. Worst has been 10.8 going uphill in 35 mph head wind. Can average 16 with everything right. 2006 Honda Ridgeline with 100k 1/3+ towing.

14.5 MPG with 2011 Ford Super Duty 250 diesel pulling 2011 27 international.
Average overall on trip through mountains Georgia to New York and back. Usual speed 60 - 65 mph.
Interestingly, on a side trip without the trailer, on the thruway from Rochester to Cleveland and return, (all flat land with very few stops) averaged 22.1 mpg and about 65 MPH.

2010 Tundra 5.7 Double Cab towing 2008 Classic 25fb. Looks like 11.3 mpg towing over the undulating terrain of Texas and Oklahoma with the AC on. Haven't had a chance to take it out West yet. I typically drive about 60mph, shifting between 6th and 5th gear, occasional 4th. I calculate the fuel mileage manually; odometer vs gallons pumped. Basically with the 26 gallon tank I have a safe driving range of 250 miles with reserve however the fuel warning light comes on when I've used 20 gallons.

14ish mpg with 2 kayaks, 2 bikes, and an '81 27' International at 65 MPH. Kind of ironic when my old gas truck got 10.5 empty by itself.
