    I went from a 5.9 liter Dodge getting 8 to 9 pulling my trailer, to a Duramax getting 13 to 14 pulling that same 16ft trailer. Much more power with the Duramax. The Dodge had power but when towing you could really tell it had a hard time on bigger hills or on longer gradual hills in hwy traffic it was hard to maintain hwy speeds unless I dam near kept it to the floor. Even then it would shift up and down. My diesel pulls it very easily and doesn't constantly shift. I can accelerate from 65 to 85 with a push of the pedal if I need to.

    I also have a sloped driveway that I have to back up into with my truck and trailer. Its not a steep slope, but it is enough that would make my dodge struggle and the engine temp and trans temp would get near the red and on occasion the trans temp light would come on. I can back my Duramax and trailer up the same driveway and barely have to give it any throttle. It will almost go up at an idle.

    I never worked my Dodge hard until I started using it for landscaping. Then when I did it started to fall apart. Trans started to not want to shift properly, rear end noise and shudder etc. Are diesels going to give you a major difference in Mpg vs a gas? No, maybe 3 to 4 mpg more. But the ease of towing and the ease at which you can stop, is well worth it.

    1/2 ton trucks are made for occasional work, picking up a few pieces of lumber and plywood for the do it yourself person. Maybe towing the boat to the lake once a week. Work them everyday and they fall apart.

    One more thing to consider that has been talked to death on the diesel truck forums, when dealing with Mpg on a diesel. Driving habits definitely have a major effect on Mpg. I have played around with my diesel and have found it to be true, the faster you drive and the harder you drive the less Mpgs. I can pull my trailer with my Duramax and make my Mpgs fluctuate as much as 3 to 4 mpgs simply by driving one way or another. Statements like Quote: Funny thing is a friend has a 2004 Ram with the Cummins Diesel and he pulls a simular trailer on the same roads, he gets 9 mpg. And my truck pulls the load with the same authority as his does. So much for diesels being better................
    Don't mean much because it has alot to do with his driving habits. And to say that your truck pulls with the same authority as a diesel, you need to get a grip on reality. No offense.

    Just my opinion.

    Put a 10,000 pound travel trailer behind both trucks and you'll see why the diesel is better real quick. :hammerhead:

    2006 F250 4x4 6.0L PSD pulling my 6.5x16 trailer. 14mpg towing the trailer. Can't really give much else though one highway trip last year I averaged about 18.5 staying at 65-70 mph. Its primarily a work truck so it don't see much non towing driving except for estimates and such.

    2005 2500HD 8.1L V8, empty gets 12.5-13 highway, 9 city. loaded, it gets the exact same, you can always depend on that engine to cost a lot to drive. I still think it's pretty good, that and engine with 496CI of displacement and dam near 500 foot pounds of torque, in a 6500lb truck can go 12 miles on just one gallon of fuel

    No doubt the diesel would be better..... it comes down to torque and the diesel usually has more, and what it does have it has at low rpms.

    The saving grace for my Toyota is the 6 speed transmission, that coupled with the over 400 pounds of torque, is why my truck will pull a simular weighted ( 7500 lbs ) trailer with the same authority as my friends diesel ram.

    I love to hear all the diesel junkies try to tell everyone that diesel trucks are far better than gasoline trucks. I used to think the same thing, even owned two Diesels in a row and liked em both. But for my needs I am glad not to have a diesel and do not feel like I am giving up anything by using a gasser

    12 empty or loaded on E-10, 14 on 87 octane straight gas. 2001 8.1 Ext cab dually 3500 with 4.10 gears. But it's fun drag racing Dodges up a 5% grade. :D Drop out of 5 into 4 and go.

    If you get tired of the 8.1/496, you can always drop in a 572 crate motor. :)

    My chevy 3500HD dually dump 454 gets a cool 5 to 6 MPG pulling the 20' lawn trailer. Maybe 1 mpg better w/o the trailer.

    My '08 GMC 2500HD gets around 12 in town and 14 on the highway. Haven't really done much towing with it yet, other than my small trailer.
