Yep, with a truck heavier than yours. The truck alone weighs 10,000 lbs (its a 2001 Dodge Ram 3500 4x4 DRW cab chassis with the Cummins HO with the six speed manual outfitted with a dump bed).

That truck has pulled loads heavier than your trailer numerous times, and can easily get better than 10 mpg doing it, usually getting around 12 mpg with the heaviest loads. I am sure your truck is more powerful and faster and has more fancy do dads, but we use this truck for work, not loafing around with an RV, although it has towed a fifth wheel RV trailer outfitted with a gooseneck adapter on a few occasions.

My point is, 10 mpg is horrible for diesel engines that just a few years ago could get mid teens pulling similar loads, albeit slower. Ford will be glad to get that new scorpion diesel under the hood.

I have an 2008 F450 with 4.3 rear end. It is a Job 1 truck built in May of 2007 with 30,000 miles. It is in for the first re flash of the PCM powertrain control module. This is a computer controlled engine as is all modern diesel engines. The EPA is mandating emission requirements that choke the life out the all new diesel engines. Ford is spending big bucks to ensure that we can get the maximum performance and economy from the new 6.4 liter diesel staying within government requirements. Ford is listening to the loyal customers by continuing to improve their products well after the sale. I will gladly drop my truck in for a 30 minute PCM update that will improve my trucks performance.
I bought another Ford because I wanted a fantastic truck with looks and guts. The F450 product is in a league by itself.

BTW I am getting 12.9 mpg hand calculated with the old math empty some city mostly highway. I can't wait for service pack 1!

Well Said!

If you are going to knock Capt. Skup's F-450 then knock it with a comparable truck/5er, not a 2001 dump truck.
