    I owned a 2001 f250 cc lb 4x4 5.4l gas with 3.73 limited slip diff and pulling 7k 6 days a week got 8mpg
    Now i own a 2004 f350 srw cc lb 4x4 6.0 with 3.73 limited slip diff pulling 7k 6 days a week and now getting 14 mpg in the hills of sc pa.
    Lastly my buddy's truck which i got to borrow is a 2002 f250 cc sb 4x4 with 4.10 limited slip and pulling 7k got 9 mpg.
    So it is more than just the engine you need to consider 4.10 will pull easier but uses more fuel because engine rpms are higher
    Your 08 has crappy mileage because of the dpf filter because someone decided that cutting soot by 50% by burning 50% more fuel makes sense.

    duramax diesel's are known for getting great fuel economy while towing, especially with efi live tunes in them, pretty normal stuff here it's actually simple math....my dad's 95 extended cab long bed with with 100 gallon aux fuel tank got 20mpg towing a 20 ft equipment trailer to nj with a monte carlo ss on it, and 22 on the way back empty trailer. doing about 70 the whole way. The more power you have the less you push the throttle to maintain speed, and accelerate, therefore the engine doesn't have to work as hard and you get better fuel economy. I run a 96 7.3 powerstroke with 272,000 of reliable service every single day. not the fastest truck or very good on fuel towing but it works every day during the spring, summer and fall and to me that is what counts, i know a gas truck wouldn't be able to move some of the stuff i tow with my truck. or it would be going very very slow up some of the hills around me. getting 4 mpg probably.

    delete your dpf and cat, and put a spartan tune in your truck probably the 250hp tune and watch your fuel economy double depending on what gears you have in the axles. my buddy did it with his 2009 f350 ext. cab short bed, he gets 25-27 on the highway hand calculated not towing, but i'm sure towing he still probably gets close to 20.

    Haven't read all the replies but being you are in OKC I would get CNG. Bought 1 and look to change all 3 of my trucks to CNG. The saving are out of this world.

    That isn't the case with the Dodge. It gets better mpg on mild +60 hp towing than on hot +175hp. Empty it does better on hot.

    I am seeing CNG as an option these days on new trucks too. How do you refill?

    There is a station 1.5 miles and 3 miles away from my home. The f450 I bought is dedicated with 30 gallon capacity. So a range of 350 to 400 miles. Soon as I get 3 to 4 vehicles I will do the home fuel station.
