KD4UPL, I guarantee if you work out your MPG on every fill up there will be a difference in the results. There being only an average can be used to evaluate a trucks fuel economy and overall MPG. If you are claiming you never get less than 10 mpg, you are driving a 3/4 ton, the Duramax in a 1 ton and c400 Kodiac deliver no more than an averaged 9.8 mpg. Could it be your driving a 3/4 ton and mostr of the time your truck is bobtail?

I wonder how the numbers and practicalities would work out in these two scenarios, pros and cons, MPG, etc....loaded weight of fifth wheel close to the same length + type of truck. I know that the MPG varies from engine to engine, but just average ball-park type figures....if that is possible.
1. 13K + 2009 F350
2. 18K + 2009 F450
Thanks for your input!

Tow mileage is useless without weight and size of 5er!

The 6.4 is not noted for fuel efficiency. The 350 would have 3.73 diff and the 450 would be 4.30. I'm pulling 15,000 with TV in sig and would be happy if I averaged 9 mpg. I do feel there is a difference in fuel quality which also affects mpg besides the wind smoothness of the road and terrain.
There is also the problem with fuel availability as the 6.4 is only cleared for 5% bio and in some areas the fuel stations all have up to 20% bio stickers on their pumps.
I would love to trade my 09 6.4 for the newer 6.7 just to avoid problems with bio-fuel.
I have had 10 mpg on occasion flat ground good road and 55 mph, hasn't happened too often.

Prior to buying a 5th wheel, We spent hours researching for the best tow vehicle and best fuel economy available. As usual I was told Oh buy Diesel, It will give you the power for climbing. That is true but overall if you have a Diesel it costs you more in Fuel purchase and repairs. I have also read the Myth Busters report that Wings and other type of deflectors don't work.
We'll I beg to differ about Diesel is better and air deflectors don't work. I average 10.2 mpg using 87 octane gas and a Wing adjusted to push the air over the trailer. Prior to using the wing I averaged 8.5 mpg my average speed is 55. So I prefer the 454 and the wing over diesel especially as most diesel users don't even get 9 mpg on a good day. Oh and as for pulling power, I can climb like the best without problems.
Now if you want to run down the freeway at 75 your fuel range will drop drastically. One of the reasons the old 55 mph was incorporated was to save fuel, It worked then and it works now.
But overall if you reduce your speed you'll increase your range.
Also note the price difference between Gas and Diesel, and compare and price. Gas is on average 60 cents cheaper than Diesel, However I have seen Diesel as much as 92 cents a gallon more than Gas. Of which there is no justification, Diesel is cheaper to produce than Gas and the only reason it is costlier is profiteering.
